Pin Functional Descriptions
1. VCC
This is the device supply voltage. For 5V to 12V fans this
can be supplied directly from the Fan Motor supply. For
fans likely to run in excess of the 18V maximum rating
for the device this will be supplied from an external
regulator such as a zener diode.

The rotor position of the Fan Motor is detected by a Hall
sensor whose output is applied to these pins. This
sensor can be either a 4 pin ‘naked’ Hall device or a 3
pin buffered switching type. For a 4 pin device the
differential Hall output signal is connected to the H+
and H- pins. For a 3 pin buffered Hall sensor the Hall
device output is attached to the H+ pin whilst the H- pin
has an external potential divider attached to hold the
pin at half V
