WRITE EXTENDED COMMAND BYTE
Data Sheet
In the write extended command byte operation, the master
device writes to one of the three extended registers of the slave
device, as follows:
7.
8.
The slave asserts an acknowledge on SDA.
The master asserts a stop condition on SDA to end the
transaction.
1.
The master device asserts a start condition on SDA.

REGISTER
2.
3.
4.
The master sends the 7-bit slave address, followed by the
write bit (low).
The addressed slave device asserts an acknowledge on SDA.
The master sends the register address byte. The MSB of
this byte is set to 1 to indicate an extended register write.
The two LSBs indicate which of the three extended registers
is written to (see Table 8). All other bits should be set to 0.

Name
EN_ADC_OC1
EN_ADC_OC4
Function
LSB, enabled if a single ADC conversion on the I channel exceeds the threshold set in the ALERT_TH register.
Enabled if four consecutive ADC conversions on the I channel exceed the threshold set in the
ALERT_TH register.

EN_HS_ALERT
Enabled if the hot swap operation either has latches off or enters a cooldown cycle because of an
overcurrent event.
3
0
EN_OFF_ALERT
Enables an alert if the hot swap operation is turned off by a transition that deasserts the ON pin or by
an operation that writes the SWOFF bit high.

0
CLEAR
Clears the OFF_ALERT, HS_ALERT, and ADC_ALERT status bits in the STATUS register. The value of these
bits may immediately change if the source of the alert is not cleared and the alert function is not disabled.
The CLEAR bit self-clears to 0 after the STATUS register bits are cleared.

Bit
[7:0]
Default
FF
Function
The ALERT_TH register sets the current level at which an alert occurs. Defaults to ADC full scale. The ALERT_TH 8-bit value
corresponds to the top eight bits of the current channel data.

SWOFF
Function
LSB, forces the hot swap operation off. Equivalent to deasserting the ON pin.
