AH5794
SINGLE PHASE HALL EFFECT LATCH FAN MOTOR DRIVER
Description
The AH5794 is a single chip solution for driving single-coil
brushless direct current (BLDC) fans and motors. The

interference (EMI) providing a low noise solution.
Low operating voltage down to 1.8V allows motor speed to be

To help protect the motor coil, the AH5794 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.
A Tachometer output is provided by open-drain Frequency
Generator (FG) Pin which allows external interface to monitor

The AH5794 is available in space saving and low profile
TSOT26 and U-DFN2020C-6 packages.
