Definition
This pin is an external voltage input pin used to supply power interfaces to the
SPI bus.
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.
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 35 mΩ high side power output pins to the load.
N/A
Input
No Connect
Fail-safe Input
These pins may not be connected.
This input enables the watchdog timeout feature.
