Definition
These pins are the ground for the logic and analog circuitry of the device.
Positive Power Supply This pin connects to the positive power supply and is the source of operational
power for the device.
Serial Output
High Side Outputs
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.
Protected 35mΩ high side power output pins to the load.
N/A
Input
No Connect
Fail-safe Input
This pin may not be connected.
The value of the resistance connected between this pin and ground
determines the state of the outputs after a watchdog timeout occurs.
