AH5795
SINGLE PHASE HALL EFFECT LATCH SMART
FAN MOTOR CONTROLLER
Description
The AH5795 is a single chip solution for driving single-coil
brushless direct current (BLDC) fans and motors. The

integrated full-bridge driver output stage uses soft switching
to minimize audible switching noise and electromagnetic

interference (EMI) providing a low noise solution.
Motor speed can be controlled by either changing the duty

ratio of the PWM signal at the PWM pin or by varying the
supply voltage at Vdd pin.

To help protect the motor coil, the AH5795 provides Rotor
Lock Protection which shuts down the output drive if rotor
lock is detected. The device automatically re-starts when the
rotor lock is removed. Over temperature shutdown provides
thermal protection for the device.
TSOT23-6
(Top View)
A Tachometer output is provided by open-drain Frequency
Generator (FG) Pin which allows external interface to monitor
motor rotation or speed. The FG output is the magnetic
change frequency.
