Addr/Therm
Open-drain output that can be used to turn on/off a fan or throttle a CPU
clock in the event of an overtemperature condition.
The pin at power-up determines the SMBus slave address according to the
pull-up resistor value as shown in Tabl e 1.
This pin must have a pull-up resistor connected to the same voltage as V
DD
or tied to GND (pin cannot float).
Total capacitance on this pin must be <100 pF.
Note: By tying Addr/Therm
to ground, the device functions as one address
device only. The Therm functionality is then not available. The address for
device STTS751-0 is 72h and the address for device STTS751-1 is 76h.
