Open-Drain Digital Output. Connect to system shutdown. Pin activates when
temperature conversion value exceeds programmed limit. Several power-on-default
limit values are available.
Connect to a low-noise +3.3 ± 0.3 V
0.1 µF ceramic capacitor in parallel with a 100 pF ceramic capacitor. A bulk
capacitance of 10 µF needs to be in the vicinity of the LM96163's V
Connect to the anode (positive side) of the remote diode. A 100pF capacitor can be
connected between pins 3 and 4.
Connect to the cathode (negative side) of the remote diode. A 100pF capacitor can
be connected between pins 3 and 4.
Open-Drain Digital Output. Connect to fan drive circuitry. The power-on default for
this pin is low (pin 4 pulled to ground).
This is the analog and digital ground return.
This pin is an open-drain ALERT output.
Tachometer input for measuring fan speed. Note the TACH input is disabled upon
power-up and needs to be enabled for use by setting TCHEN bit 2 of Configuration
Register 03h.
This is the bidirectional SMBus data line.
Digital Input. This is the SMBus clock input.
