J_Filter| Closed by default
J_IS| 1-2 closed by default If 2-3 is closed:

· J_Filter has to be opened!

· Sense directly switched to IS (Filter disconnected)

J_GND| 1-2 closed: R_GND = 150 Ω (default) 3-4 closed: R_GND = 50 Ω

5-6 closed: R_GND = 0 Ω

J_IN2| 3-2 closed by default. If 1-2 is closed:

· Connect PROFET 2

J_IN3| 3-2 closed by default. If 1-2 is closed:

· Connect PROFET 2

J_VDD| 1-2 closed (default VDD via µIO-Stick):

· Use +5VµIO (USB) as digital supply voltage

2-3 closed:

· VDD via external supply

J_ch0 1| Closed if 4 Channel SPOCTM+2 is used:
| · OUT0 and OUT1/0 in parallel.
---|---
J_ch3 1| Closed if 4 Channel SPOC+2 is used:

· OUT4/3 and OUT5/3 in parallel.

Output channel 0 if J_ch0 is closed

OUT2/1 1| Output channel 2 if J_ch0 is open,

Output channel 1 if J_ch0 is closed

OUT3/2 1| Output channel 3 if J_ch0 is open,

Output channel 2 if J_ch0 is closed

OUT4/3 1| Output channel 4 if J_ch3 is open,

Output channel 3 if J_ch3 is closed

OUT5/3 1| Output channel 5 if J_ch3 is open,

Output channel 3 if J_ch3 is closed

If 4-Channel-SPOCTM are used J_ch0 and J_ch3 had to be closed, otherwise (6-Channel-SPOC) opened.
If Jumpers J_IN2 and J_IN3 are set to 1-2: SPOCTM Outputs EDD and EDO can control the PROFET.

Figure 19 below illustrates a possible test setup. The examples in 2.3.1 and 2.3.2 refer to this setup.

Infineon-SPOCTM+2-Multichannel-SPI-High-Side-Power-Controller-
FIG-18

Example 1: Switching on 4 lights step by step with 1 Second delay

Switch to SPI view and select register OUT (See Figure 20)
Tick the WRITE?-Box and select no Output (See Figure 21)
Click ADD CMD and your command is added to the command list (See Figure 22)
Select OUT0 in the WRITE-Box (See Figure 23)
Click ADD CMD (See Figure 24)
Change the delay of each command to 1000 (delay of 1 second, See Figure 25)
Repeat the last three steps until you reach OUT3 (See Figure 26)
Switch to STD view (See Figure 27) and select a channel (0 – 3) at IS MUX (See Figure 28)
Switch back to SPI view and click the START-button (See Figure 29)
The response of the SPOCTM+2 is shown in the response list (See Figure 30)

Example 2: Let one light blink 10 times

Description t [ms] T_ON Duration light on 500
T_OFF Duration light off 500

Switch to SPI view and select register OUT (See Figure 31)
Tick the WRITE?-Box and select OUT0 and click ADD CMD (See Figure 32)
Select no output in the WRITE-Box and click ADD CMD (See Figure 33)
Also typing in commands directly is possible (See SPOCTM+2 datasheet for command reference)
o E.g.:
- The command 80h means Write no output to OUT
- The command 81h would mean Write to OUT and set OUT0 high.
- See Figure 32 above
Change the delay of command 81 to T_ON, the delay of command 80 to T_OFF (See Figure 34)
Change loop all commands x times to 10 (See Figure 35)
Switch to STD view (See Figure 36) and select a channel (0 – 3) at IS MUX (See Figure 37)
Switch back to SPI view and click the START-button (See Figure 38)
The response of the SPOCTM+2 is shown in the response list (See Figure 39)
