Input for monitoring a fan tachometer input.
Input for monitoring a fan tachometer input.
Input for monitoring a fan tachometer input.
/Interrupt output to indicate a thermal and/or
voltage event.
Input for monitoring a fan tachometer input.
If in Address Select Mode, determines the
SMBus address of the device.
PWM Output 1 controlling speed of fan.
When in XOR tree test mode, functions as
XOR Tree output.
PWM Output 2 controlling speed of fan.
/Interrupt output to indicate a thermal and/or
voltage event.
PWM Output 3 controlling speed of fan.
If pulled to ground at power on, enables
Address Select Mode (Address Select pin
controls SMBus address of the device).
Positive Power Supply. Nominal 3.3V.
VCC is monitored by the Hardware
Monitoring Block.
(Can be powered by +3.3V Standby power if
monitoring in low power states is required.)
Analog Ground.
Buffer types per function on multiplexed pins are separated by a slash “/”. Buffer types in
parenthesis represent multiple buffer types for a single pin function.
This analog input is backdrive protected.
