8, 25
GND
Ground
Ground
These pins, internally shorted, are the ground for the logic and analog circuitry
of the device. These ground pins must be also shorted in the board.
9, 33
VPWR
Power Positive Power Supply This pin connects to the positive power supply and is the source of operational
power for the device. Pins 9 and 33 must be externally connected.

High Side Output
Protected 10 m high side power output pins to the load.
Protected 25 m high side power output pins to the load.
No Connect
Fail-safe Input
This pin may not be connected.
This input enables the watchdog timeout feature.
27
CSNS
Output
Output Current
This pin reports an analog value proportional to the designated HS[0:3] output
Monitoring
current or the temperature of the GND flag (pin 14). It is used externally to
generate a ground-referenced voltage for the microcontroller (MCU) . Current
recopy and temperature feedback is SPI programmable.
28
IN0
Input
Direct Inputs
Each direct input controls the device mode. The IN[0 : 3] high side input pins
29
IN1
are used to directly control HS0 : HS3 high side output pins.
30
IN2
The PWM frequency can be generated from IN0 pin to PWM module in case
31
IN3
of external clock is set.
32
FSB
Output
Fault Status
This pin is an open drain configured output requiring an external pull-up
(Active Low)
resistor to VDD for fault reporting.
