MSB
On each SPI communication, an 8-bit command word is sent to the 33880 and an 8-bit fault word is received from the 33880.
1 = Output Command On
0 = No fault
1 = Fault.
OUT7
OUT6
OUT5
OUT4
Fault reported by Serial Output (DO) pin.
DO pin reports short to battery/supply or overcurrent condition.
Not reported.
DO pin reports output OFF open load condition.
Total device shutdown at V
All outputs assuming the previous state upon recovery from overvoltage.
Only the output experiencing an overtemperature fault shuts down. Output assumes previous state
upon recovery from overtemperature.
