8, 25

GND

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.

Output

High Side Output

Protected 25 m

 high side power output pins to the load.

14, 15, 16

HS1

Output

High Side Output

Protected 10 m

 high side power output pins to the load.

17, 18, 19

HS0

Output

High Side Output

Protected 10 m

 high side power output pins to the load.

20, 21, 22,

HS2

Output

High Side Output

Protected 25 m

 high side power output pins to the load.

N/A

No Connect

This pin may not be connected.

FSI

Input

Fail-safe Input

This input enables the watchdog timeout feature.

CSNS

Output

Output Current

Monitoring

This pin reports an analog value proportional to the designated HS[0:3] output

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.

IN0

IN1

IN2

IN3

Input

Direct Inputs

Each direct input controls the device mode. The IN[0:3] high side input pins

are used to directly control HS0:HS3 high side output pins.

The PWM frequency can be generated from IN0 pin to PWM module in case

of external clock is set.

FSB

Output

Fault Status

(Active Low)

This pin is an open drain configured output requiring an external pull-up

resistor to VDD for fault reporting.
