FUNCTIONAL DESCRIPTION

SPI DEFINITION

Table 8. Fault Operation

Serial Output (DO) Pin Reports

Overtemperature

Fault reported by serial output (DO) pin.

Overcurrent

DO pin reports short to battery/supply or overcurrent condition.

Output ON Open Load Fault

Not reported.

Output OFF Open Load Fault

DO pin reports output OFF open load condition only with Open Load Detection Current enabled.

DO pin will report “0” for Output OFF Open Load Fault with Open Load Detection Current disabled.

Device Shutdowns

Overvoltage

outputs assuming the previous state upon recovery from overvoltage.

Overtemperature

Only the output experiencing an overtemperature shuts down. Output assumes previous state upon

recovery from overtemperature.
