   2. Do not turn on the power supply.

4. Turn on the +24V supply and +5V supply and verify that LED_VDDL (green), LED_V5 (green), and LED_VL (green) are illuminated, which indicates that the EV kit logic-side supply VDDL, MAX14918A V5 and VL are present and MAX14918A is powered up normally.

5. Connect the positive output of the functional generator to TERM2 Pin 2 test point, which is the isolated IN1 input of the MAX14918A. Connect the negative output of the functional generator to TERM2 Pin 6, or any GNDL test point on the logic-side of the EV kit. Set the functional generator output at 1kHz, 50% duty-cycle square wave with output high voltage of 5V and low voltage of 0V. Do not enable the functional generator output.

Detailed Description of Hardware

The MAX14918A EV kit provides an easy-to-use and flexible solution to evaluate the MAX14918A, parallel controlled quad low-side switches with reverse-current detection, for industrial applications. The EV kit comes with field-side terminal blocks to allow connections to industrial loads for easy evaluation of the device and the system. The EV kit can be powered by a single +5V logic- side supply, which powers the onboard isolated DC-DC converter generating an isolated +5V analog supply as the main supply for the MAX14918A.

The MAX14918A EV kit comes with an n-channel MOSFET installed to protect against reverse current at outputs. All field-side outputs and field-side supply are protected against line-to-ground surges up to ±1.2kV/42Ω per IEC 61000-4-5.

This MAX14918A EV kit user guide must be used with the MAX14918/MAX14918A data sheet.

For the latest versions of the documents, refer to the MAX14918A product page.

Power Supplies

The EV kit has two power domains, the logic side, which is powered from a logic-side +5V DC supply connected to PWR2 terminal block or VIN and GNDL test points, and the field side, which is typically powered from an external +24V DC supply connected to PWR1 terminal block or 24V_FIELD and COM test points.

The logic side of the MAX14918A EV kit is powered by applying an external +5V DC voltage to PWR2 terminal block or VIN and GNDL test points. It is the logic-side supply for the onboard isolated DC-DC converter ADuM6028, which generates an isolated +5V output at the field side to power the MAX14918A V5 when J6 is closed (see Table 1). The logic-side +5V supply also powers the logic-side of the digital isolator ADuM340E VDDL when J8 is closed (see Table 1).
If a different logic level than +5V is required at the logic side, J8 can be removed and apply a +2.25V to +5.5V DC voltage to VDDL (terminal block TERM2 Pin 1) to supply the ADuM340E and set its logic level.

When the field-side +24V supply is provided, the MAX14918A is powered by VDD. In this case, the MAX14918A internal regulator is enabled to provide low voltage output at V5 (5V, nominal), which is connected to VL, the logic supply of the MAX14918A, when J1 is closed (see Table 1). VL also powers the field- side of the digital isolator ADuM340E. If a different logic level than +5V is desired on the MAX14918A digital pins, J1 can be removed and apply a +1.62V to +5.5V DC voltage on the VL test point to power the MAX14918A VL and set the device logic level.

When the field-side +24V supply is not connected or the MAX14918A VDD is connected to field-side ground (GNDF), the MAX14918A main analog supply V5 can be powered by either an external +5V DC voltage through V5 and GND test points, or by the onboard isolated +5V supply generated by the ADuM6028 when J6 is closed (see Table 1).

The MAX14918A EV kit can be powered by a single +5V DC supply at logic side through terminal block PWR2. The logic side ADuM6028 and ADuM340E are both powered by the +5V with J8 in 1-2 position. The isolated field-side +5V generated by the ADuM6028 provides the main analog supply to the MAX14918A V5 with J6 in 1-2 position, and to the field-side logic supply VL with J1 in 1-2 position. For more details, see the MAX14918A EV Kit Schematic section.

MAX14918A Output Control

The field-side IN1 to IN4 inputs of the MAX14918A are controlled by TERM2 Pin 2 to Pin 5, which are the logic-side IN1 to IN4 inputs. These signals are isolated by the onboard digital isolator ADuM340E before feeding into the MAX14918A.
The field-side inputs IN1 to IN4 can be monitored using the IN1 to IN4 test points. The MAX14918A switching outputs OUT1 to OUT4 are controlled by the IN1 to IN4 control inputs, respectively. For more details, see the MAX14918A EV Kit Schematic section.

All the MAX14918A output switches are turned off regardless of their respective input state when the global DIS input is set to low. When DIS is set to high, all outputs are switched according to their associated input state. The DIS input has a weak internal pull-down. When jumper J3 is open, the DIS input is set to low by the internal pull-down, thus all outputs are turned off. When jumper J3 is in 1-2 position, the DIS input is connected to VL, thus all outputs are switched according to IN1 to IN4 input states.

The latch enable input (LATCHEN) allows the MAX14918A to be used in transparent or hold mode. When the latch enable is high (jumper J2 in 1-2 position), the output (OUT) is not affected by its associated input (IN). When the latch enable is low (jumper J2 in open position), the input (IN) to output (OUT) control is transparent. The LATCHEN input has a weak internal pull-down.

Slew Rate Control

The MAX14918A features output slew-rate control on turn-on edges. When the HISLEW input is low (jumper J4 in open position), output transitions are slower, and the MAX14918A operates up to 50kHz switching frequency. The HISLEW input has a weak internal pull-down. The slow slew-rate mode is useful in applications where the load is capacitive and is connected through a long cable.

When the HISLEW input is high (jumper J4 in 1-2 position), the output transitions are much faster, and the MAX14918A can operate up to 500kHz switching frequency. This mode is useful in applications where the device drives resistive loads.

Current Limit Setting and INRUSH Mode

The MAX14918A features resistor-settable active current limiting, common to all output switches (OUT1 to OUT4). When the current across the switch exceeds the current limit, the load current is limited by the low-side switch. The current limit is set by the RCLIM resistor between RCLIM pin and device ground (GNDF). The MAX14918A EV kit provides three current limit options, selected by jumper JMP1. When JMP1 is in 1-2 position, the current limit is set to 216mA (typ) as a100kΩ resistor is connected between RCLIM pin and GNDF. When JMP1 is in 1-3 position, the current limit is set to 403mA (typ) as a 53.6kΩ resistor is connected between RCLIM pin and GNDF. When JMP1 is in 1-4 position (default), the current limit is set to 800mA (typ) as a 27kΩ resistor is connected between RCLIM pin and GNDF. For the equation to calculate the current limit ILIM based on the RCLIM resistor value, refer to the MAX14918/MAX14918A data sheet.

The MAX14918A offers the inrush mode, which supports loads that draw higher current during turn-on. In the inrush mode, each switch provides at least double the current set by the RCLIM resistor for the inrush duration of 10ms (min).
After the inrush period, the switch current limit reverts to the value set by RCLIM. The inrush mode is enabled when the INRUSH pin is set to high (jumper J5 in 1-2 position) and disabled when the INRUSH pin is set to low (jumper J5 in open position). The INRUSH input has a weak internal pull-down.

Reverse-Current Protection

The MAX14918A features reverse-current detection with OUT switch either in on or off state, which is signaled by the REV logic output. A reverse current on any output (OUT) can happen when the field supply is miswired with a reverse polarity, or when a direct reverse connection is between OUT_ and COM.

When any reverse current more than 150mA (typ) is flowing out of any output, the REV output transitions low and the MAX14918A automatically turns off all four outputs. The REV output drives the gate of the onboard n-channel MOSFET (Q1) low, which opens the MAX14918A device ground (GNDF) to the field COM (COM) connection, therefore stopping the reverse current flow. The REV output is held low, and all outputs remain off for the auto-retry duration of 2 seconds(typ) before the REV output is pulled high again and outputs are turned back on based on the input state to see whether the reverse-current condition is still present. If the reverse-current condition is still present and a reverse current is again detected, the REV is turned low again, and all outputs are turned off for another 2 seconds. For more details on the reverse- current detection feature, refer to the MAX14918/MAX14918A data sheet.

The EV kit also protects against reverse polarity on the MAX14918A VDD pin by implementing reverse protection diode D5. For more details, see the MAX14918A EV Kit Schematic section.

Diagnostic Features

The MAX14918A features a global fault indication pin, FAULT. It is an open- drain logic output that transitions low when the MAX14918A detects a fault condition and is pulled high when the device exits fault status. A red LED is connected in series with the pull-up resistor on the FAULT pin to indicate when fault conditions are detected, which include chip thermal shutdown, any of the output switches that are turned on in thermal overload, reverse current detected at any of the outputs, V5 UVLO or short-circuit detected on the RCLIM pin.

Another red LED is implemented between the MAX14918A local ground (GNDF) and field return connection (COM). It is turned on when any reverse current is flowing from COM to GNDF, which indicates that a reverse current fault on the MAX14918A EV kit. For more details, see the MAX14918A EV Kit Schematic section.

Galvanic Isolation

The MAX14918A EV kit uses an isolated DC-DC converter and a digital isolator to provide galvanic isolation for both power and data between the logic side and the field side. The ADuM6028 is a low-emission, 5kV isolated DC-DC converter that generates an isolated 5V (VISO) on the field side (GNDF) when powered by a 5V supply (VDDP) on the logic side (GNDL). The MAX14918A can be powered by VISO when it is connected to V5 and VL with jumper J7 in 2-3 position, and J6 and J1 in 1-2 position (see Table 1). This allows the MAX14918A EV kit to be powered by a single logic-side supply with no external field-side supply needed.

The digital isolation is achieved by the ADuM340E, 5.7kVRMS quad digital isolator, which provides data isolation on IN1 to IN4 input control signals. The isolator has two power supplies (VDD1 and VDD2), which operate between +2.25V to+5.5V and provide voltage translation as well as galvanic isolation. The logic-side VDD1 of the isolator can be the same 5V supply applied to the ADuM6028 VDDP and GNDL when J8 is in 1-2 position, or a different voltage level can be applied to VDD1 through connector TERM2 Pin 1 when J8 is open. The field-side VDD2 of the isolator is powered from VL and GNDF, same as the MAX14918A logic supply. When testing isolation performance, users must take care that there is no short connection between GNDF and GNDL through a multichannel oscilloscope ground connection.

IEC 61000-4 Transient Immunity

Each output of the MAX14918A is protected against IEC 61000-4-5 1.2μs/50μs surges up to ±1.2kV/(42Ω + 0.5μF) lineto-ground, IEC 61000-4-2 ESD contact discharge up to ±8kV line-to-ground, and IEC 61000-4-2 ESD air-gap discharge up to ±25kV line-to-ground without the need for external protection diodes from OUT_ to GNDF. The MAX14918A EV kit comes with an external n-channel MOSFET (Q1) for reverse-current protection. A TVS diode (D1) is placed in parallel to Q1 to protect it from high voltage transients such as surge or ESD events. Another TVS diode (D5) provides protection against surges and ESD transients applied through 24V_FIELD and COM terminal block and diode D6 blocks the reverse current to the VDD pin of the MAX14918A during negative transients.
