AH280  
Hall-Effect Smart Fan Driver  
„ Features  
„ General Description  
AH280 is the integrated Hall sensor owned two  
complementary outputs for motor’s coil driving, auto  
locked shutdown and auto restart functions.  
Functional block diagram includes that a regulator  
with temperature-compensated band-gap, an  
on-chip Hall voltage generator, a comparator, a  
Schmitt trigger and two current output drivers. The  
regulator can provide wide operational voltage  
range. The Hall voltage generator is to amplify the  
Hall voltage due to Hall effect. A Schmitt trigger is  
to provide switching Hysteresis for noise rejection.  
To avoid coil burning, rotor-lock detection circuit will  
shutdown the output driver if detect rotor-lock status.  
A rotation recovery circuit is to restart the motor  
after rotor-lock is removed. In addition, the auto  
re-start time is flexible by adjusting the capacitance  
(CT).  
- On chip Hall plate  
- Built-in Zener diode protection for output driver  
- Built-in protection diode for power reverse  
connecting  
- Rotor-lock detection  
- Automatically restart after release of motor  
locking  
- Adjustable auto restart time  
- Operating voltage: 3.5~20 V  
- Max Output current: IO(AVE) = 500mA  
- Packages: SIP-5L, SOP-8L, SOP-8L EP  
- Less external component
