SMBus clock input.
Supply Voltage, 3.0V to 3.6V.
Anode connection for remote temperature diode.
Cathode connection for remote temperature diode.
Logic output that can be used to turn on/off a fan or throttle a CPU clock
in the event of an over-temperature condition. This is an open-drain
output. For the EMC1002-2, this pin is sampled following power up and
the value of the pull-up resistor determines the SMBus slave address per
Table 1.2 on page
pf, and the pull-up resistor must be connected to the same supply voltage
as V
Ground.
Logic output used as interrupt, SMBus alert or as a second THERM
output. This is an open-drain output.
SMBus data input/output. This is an open-drain output.
