AH293
Low Voltage Hall-Effect Smart Fan Motor Controller
Features
General Description
- On chip Hall sensor
AH293 is a monolithic fan motor controller with Hall
sensor’s capability. It contains two complementary
open-collector transistors for motor’s coil driving,
automatic lock current shutdown, and recovery
protections. Besides, rotor-state detection (RD)
output is for speed detection.
- Rotor-locked shutdown
- Automatically restart
- Rotor-state detection (RD) output
- Built-in Zener protection for output driver
- Operating voltage: 1.8V~5.75 V
- Output current: IO(AVE) = 400 mA
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. These protecting actions are
repeated and periodic during the blocked period.
Until the blocking is removed, the motor recovers
running normally.
- Package: SIP-5L, SOT23-5L, SOT89-5L
