NAME
FUNCTION
1
12V
IN
Analog Input. Monitors 12V supply.
2
2.5V
IN
Analog Input. Monitors 2.5V supply.
3
3.3V
IN
Analog Input. Monitors 3.3V supply.

ALERT
SMBus Alert (Interrupt) Output, Open Drain. Alerts the master that a temperature or voltage limit
has been violated.
7
ADD
SMBus Address Select Input. ADD is sampled at the beginning of each I
