AH5771  
SINGLE PHASE HALL EFFECT LATCH SMART FAN  
MOTOR CONTROLLER  
General Description  
Features  
AH5771 is the integrated Hall sensor with output drivers designed  
for electrical commutation of brush-less DC motor application.  
The device is as follows: one-chip Hall voltage generator for  
magnetic sensing; the error amplifier that amplifies the Hall  
voltage; a comparator is to provide switching hysteresis for noise  
Support single-phase full wave min fan driver  
Built-in Hall sensor input amplifier  
Low voltage startup ( Vdd=2.5V )  
Lock detection and automatic self-restart  
Without external timing capacitor, Reduces the  
numbers of external component required  
Low profile package : SIP-4L  
SIP-4L: Available in “Green” Molding Compound  
(No Br, Sb)  
Lead Free Finish / RoHS Compliant (Note 1)  
rejection; the full bridge driver for sinking and driving current load.  
Internal band gap regulator is used to provide temperature  
compensated bias for internal circuits and allows  
a wide  
operating supply voltage range. The device includes features  
such as Rotor Lock Protection with rotor lock detection and  
automatic self-restart to avoid damage to the coil when the rotor  
is blocked. AH5771 is rated for operation over-temperature range  
from -40to 100and voltage range from 2.5V to 15V. The  
device is available in low profile package SIP-4L.

Note: D2 (Zenor Diode) and Capacitor C are for power stabilization, D2 is recommended to be 18Vz (option),  
C is recommended to 0.1uF ~1uF (E-Cap). D1 (reverse Diode) is for reverse voltage protection.
