VPWR
Input
Battery Input
Power supply pin to the 33879. VPWR has internal reverse battery
protection.
32
DO
Output Serial Data Output SPI control data output pin from the 33879 to the MCU. DO=0 no fault,
DO = 1 specific output has fault.

EP
Ground
Exposed Pad
Device will perform as specified with the Exposed Pad un-terminated
(floating) however, it is recommended that the Exposed Pad be terminated
to pin 1 (GND) and system ground.
