Table 15. Status Byte Operations

Bit

Name

Function

0

ADC_OC

An ADC-based overcurrent comparison has been detected on the last three conversions

1

ADC_ALERT

An ADC-based overcurrent trip has happened, which has caused the alert. Cleared by writing to Bit 4 of the ALERT_EN

register.

2

HS_OC

The hot swap is off due to an analog overcurrent event. On parts that latch off, this is the same as the HS_ALERT status

bit (if EN_HS_ALERT = 1). On the retry parts, this indicates the current state: a 0 can indicate that the data was read

during a period when the device was retrying, or that it has successfully hot swapped by retrying after at least one

overcurrent timeout.

3

HS_ALERT

The hot swap has failed since the last time this was reset. Cleared by writing to Bit 4 of the ALERT_EN register.

4

OFF_STATUS

The state of the ON/ONB pin. Set to 1 if the input pin is deasserted. Can also be set to 1 by writing to the SWOFF bit of

the CONTROL register.

5

OFF_ALERT

An alert has been caused by either the ON/ONB pin or the SWOFF bit. Cleared by writing to Bit 4 of the ALERT_EN

register.
