Name

Function

0

ADC_OC

An ADC-based overcurrent comparison is detected on the last three conversions.

1

ADC_ALERT

An ADC-based overcurrent trip has occurred, causing the alert. Cleared by writing to Bit 4 of the ALERT_EN register.

2

OC

An overcurrent condition is present (that is, the output of the current sense amplifier is greater than the voltage on the

SETV input).

3

OC_ALERT

An overcurrent condition causes the ALERT block to latch a fault, and the ALERTB output asserts. Cleared by writing to

Bit 4 of the ALERT_EN register.

4

OFF_STATUS

Set to 1 by writing to the SWOFF bit of the CONTROL register.

5

OFF_ALERT

An alert has been caused by the SWOFF bit. Cleared by writing to Bit 4 of the ALERT_EN register.
