Introduction

Product overview

• IGBT modules used in inverters for compressors and air conditioner fans are developing rapidly in response to the growing demand for energy saving, equipment miniaturization and weight reduction.
• IGBTs are devices that combine the high-speed switching performance of power MOSFETs and the high-voltage, high-current capabilities of bipolar transistors, and are expected to further develop in the future.
• Among them, the IPM (Intelligent Power Module) is a 3-phase IGBT inverter bridge circuit with integrated gate drive circuits and protection circuits.

Product concept

• 7th gen. IGBT/FWD technology realize low loss and energy saving of equipment.
• Guaranteed Tvjop=150oC allows expansion of output current.
• High accuracy short-circuit protection detection expands the overload operation range.
• Compatible pin assignments, footprints, and mounting dimensions with conventional Small IPM.
• Product lineup of 650V/15A to 35A.
• Lower total loss against conventional products by improving the trade-off between Collector-Emitter saturation voltage VCE(sat) and switching loss.
• Achieves low dv/dt and low switching loss compared to conventional products.

Internal circuit

• Optimally designed IGBT drive circuit.
• The high-side control IC (HVIC) contains a high-voltage level shift circuit.
• This product can be driven directly by MCU (microcontroller) on both the high-side and low-side arms. The voltage level of the input signals are 3.3V or 5V.
• Since the wiring length between the internal drive circuit and IGBT is short and the impedance of the drive circuit is low, no reverse bias power supply is required.
• Normally, IPM device requires a total of four isolated control power supplies: one for the lower sides and three for the upper sides. However, since this IPM has built-in bootstrap diodes (BSD), isolated power supplies for the high-sides are not needed.

Built-in protection circuit

• The following built-in protection circuits are incorporated in the product:
  • OC: Over current protection
  • UV: Under voltage protection for power supplies of control IC
  • LT: Temperature sensor output function
  • OH: Overheating protection (only applied to some products)
  • FO: Fault alarm signal output
• The OC protection circuits protect the IGBT against over current, load short-circuit or arm shortcircuit.
• The protection circuit can monitor the emitter current using external shunt resistor in each low-side IGBT and thus it can protect the IGBT against arm short-circuit.
• The UV protection circuit operates when the control power supply voltage drops below the trip voltage level. It is built into all of the IGBT drive circuits.
• The OH protection circuit protects the product from overheating. The OH protection circuit is built into the control IC of the low-side arm (LVIC).
• The temperature sensor output function is built into the LVIC and converts the detected temperature into analog voltage output.
• The FO function outputs a fault signal when the circuit detects abnormal conditions, thus making it possible to shut down the system reliably and preventing destruction by outputting the fault signal to the microprocessor unit controlling the product.

Compact package

• This product uses high heat dissipation aluminum insulated metal substrate (IMS), which improves the heat radiation.
• The control input terminals have a shrink pitch of 1.778mm (70mil).
• The power terminals have a standard pitch of 2.54mm (100mil).

Absolute Maximum Rating of Collector-Emitter Voltage

During operation, the voltage between P-N(U, V, W) is usually applied to high- side or low-side of one phase. Therefore, Use the product with the voltage applied between P-N(*) within the absolute maximum ratings. The collector- emitter voltage absolute maximum rating is described below. 1-12

VCE(chip): Since VCE(chip) cannot be measured directly, use the product with VDC(terminal),
VDC(Surge,terminal) , which is the voltage between P-N(*) terminals, within the absolute maximum ratings.
VDC(terminal): DC bus voltage (between P-N(U, V, W) terminals)
VDC(Surge, terminal): DC bus voltage at P-N(U, V, W) terminals including surge voltage generated during switching.

• Fig.1-7 shows the waveforms during short-circuit, IGBT turn-off and FWD reverse recovery. Since VDC(Surge, terminal) is different in each situation, it is necessary to set VDC(terminal) considering these situations.
• VCE(chip) is the collector-emitter voltage absolute maximum rating of the IGBT chip. VDC(Surge, terminal) is specified considering the margin of surge voltage generated by the wiring inductance inside the Product.
• Also, VDC(terminal) is specified with margin considering the surge voltage generated by the wiring inductance between the P-N(*) terminal and the bulk capacitor.
