PIN CONNECTIONS

14, 17, 23

GND

Ground

These pins are the ground for the logic and analog circuitry of the device.

VPWR

Power

Positive Power Supply

This pin connects to the positive power supply and is the source of operational

power for the device.

Output

Serial Output

This output pin is connected to the SPI Serial Data Input pin of the MCU or to

the SI pin of the next device of a daisy

-chain of devices.

HS3

HS1

HS0

HS2

Output

High-Side Outputs

Protected 35 m

Ω high-side power output pins to the load.

N/A

No Connect

This pin may not be connected.

FSI

Input

Fail-Safe Input

The value of the resistance connected between this pin and ground

determines the state of the outputs after a Watchdog timeout occurs.
