FLT_CLR is active high and it is used to reset the fault state of all devices (see also the Fault
management section and the IR22141SS datasheet).
FAULT/SD logic signal
This is an input/output logic signal, 3.3 V compatible CMOS I/O port. The logic signal is active low, tied
to connector VCC with a 10 k
as an output, it reports the power module fault (IGBT desaturation detection) or the VCC undervoltage
(see also IR22141SS datasheet for more information).
On board a red LED (DL2) indicates when the signal is active; Figure 2a shows the connection.
VCC supply pin
This is the supply pin for all the devices. On board a green LED (DL1) indicates the supply power on;
Figure 2b shows the connection.
VSS ground pin (GND)
The board ground is connected to the power module DC- pin. The VSS pin of the connector and the
devices ground pin are star-connected to the DC- pin. DC- star connection has been chosen to reduce
the noise coupled from the floating signals.
Connecting the current sensors
P1, P2 and P3 are connected with the optional shunt resistors placed on the phase output nodes.
