Pin Description
1
Positive supply voltage. DC voltage from 3.0 V to 5.5 V.
2
Diode current source (anode).
3
Diode sink current (cathode).
4
T_CRIT alarm is open-drain, active LOW output which requires an external
pull-up resistor. It functions as a system interrupt or power shutdown.
5
Power supply ground.
6
ALERT alarm is an open-drain, active LOW output which requires an
external pull-up resistor. It functions as an interrupt indicating that the
temperature of the on-chip or remote diode is above or below programmed
overtemperature or undertemperature thresholds.
7
SMBus/I2C-bus bidirectional data line. This is an open-drain output which
requires an external pull-up resistor.
8
SMBus/I2C-bus clock input which requires an external pull-up resistor.
