AH5798  
SINGLE PHASE HALL EFFECT LATCH SMART  
FAN MOTOR CONTROLLER  
Description  
Pin Assignments  
( Top View )  
The AH5798 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.

To help protect the motor coil, the AH5798 provides Rotor  
Lock Protection which shuts down 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.

SOT89-5L  
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.

Features  
TSOT25  
Supports single-coil full-wave DC fan drivers  
Built-in Hall sensor and input amplifier  
Operating Voltage: 1.8V to 5.5V  
Applications  
Soft switching for low noise DC fan motor applications  
Rotor Lock Protection (Lock detection, output shutdown  
and automatic re-start)  
3.3V / 5V Min. BLDC Cooling Fans  
Netbook/ Notebook BLDC fans  
Thermal protection  
Low Voltage/ Low Power BLDC Motors  
Tachometer (FG) output  
No external timing capacitor - Reduces the numbers of  
external components required  
Low profile packages: SOT89-5L and TSOT25
