IRMD22381Q
Input logical signals HINU/N, LINU, HINV/N, LINV, HINW/N, LINW, BRIN/N, SD
These logic inputs are 5V and 3.3 V compatible CMOS I/O ports. The logic signals ending with “/N” are
active low. The board is populated with pull-up and pull-down resistors (to 5V supply) in order to keep inputs
tied to supplies when controller is still inactive. HINx/N turns on the high side IGBT while LINx the low side.
When both HINx/N and LINx of the same phase are active at the same time an internal anti-shot trough
circuit turns off the output drivers.
FAULT logic signal
This is an output, open drain, logic signal. The logic signal is active low, tied to connector V
CC
with a 1k
pull-up resistor. It reports the power module fault (IGBT desaturation detection, latched signal) or the V
CC
undervoltage (unlatched).
On board a red LED (DL2) indicates when the signal is active; Figure 2a shows the connection.
DCF
Dc plus feedback voltage (DCF pin) is connected to a resistor divider tied from DC+ to V
SS
(DC-) and
clamped by a 5V zener. At DC+= 330V, DCF
≈
1.4V.
RT+ and RT-
RT+ and RT-, thermistor output, are connected to the corresponding RT+, RT- pins of the power module.
Note: RT- is starred to Vss at pin 19 of the J1 connector in the IRMD22381Q PCB.
VFHx and VFLx
Voltage feedback outputs from IRMD22381Q
Note
: further information about IR22381Q I/Os are described in details in IR22381Q datasheet.
V
CC
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.

V
SS
ground pin (GND)
The board ground is connected to the power module DC- pin. The V
SS
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.
5V
5V input supply for FAULT, VFx and inputs pull-ups.
