Functional Pin Description
Output 5 MOSFET drain pin.
Output 3 MOSFET drain pin.
Output 3 MOSFET source pin.
Output 4 MOSFET drain pin.
Output 4 MOSFET source pin.
Output 7 MOSFET drain pin.
Output 7 MOSFET source pin.
Power supply pin to the 33879. VPWR has internal reverse battery
protection.
SPI control data output pin from the 33879 to the MCU. DO = 0 no fault,
DO = 1 specific output has fault.
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.
