LINEAR INTEGRATED CIRCUIT
COMPLEMENTARY OUTPUT
HALL EFFECT FAN DRIVER
 DESCRIPTION
UTC UH288F(FG)/UH288R(RD) are integrated Hall sensors with
output drivers, mainly designed for electronic commutation of
brush-less DC Fan. This IC is using HV BCD process internally
includes the regulator, protecting diode, Hall plate, amplifier,
comparator, and a pair of complementary open-Drain outputs (DO,
DOB).
To avoid coil burning, rotor-lock shutdown detection circuit shut
down the output driver if the rotor is blocked and then the automatic
recovery circuit will try to restart the motor. This function repeats while
rotor is blocked. Until the blocking is removed, the motor recovers
running normally.
 FEATURES
* Wide operating voltage range: 4V~28V
* Output sink current up to 0.3A
* On-Chip High sensitivity Hall-effect Sensor
* Thermal Shutdown Protection
* Low Output Switching Current Noise
* -40°C ~ 85°C Operating Temperature
* Rotor-locked shutdown and automatically restart function
* For 12V and 24V DC motor / FAN systems
