Function and Connection
1
V
DD
Power Supply Input
Connect to a low-noise +3.3
±
0.3 VDC power supply, and bypass to GND
with a 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 LM63’s V
DD
pin.
Connect to the anode (positive side) of the remote diode. A 2.2 nF ceramic
capacitor must be connected between pins 2 and 3.
Connect to the cathode (negative side) of the remote diode. A 2.2 nF
ceramic capacitor must be connected between pins 2 and 3.
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.
Depending on how the LM63 is programmed, this pin is either an
open-drain ALERT output
or
a tachometer input for measuring fan speed.
The power-on default for this pin is the ALERT function.
