AH289
High Voltage Hall-Effect Smart Fan Motor Controller
Features
General Description
- On chip Hall sensor
AH289 is a monolithic fan motor controller with Hall
sensor’s capability. It contains two complementary
open-drain transistors for motor’s coil driving,
automatic lock current shutdown, and recovery
protections. In addition, rotor-state detection (RD)
output is for Rotor-state detection.
- Rotor-locked shutdown
- Automatically restart
- Rotor-state detection (RD) output
- Built-in Zener protection for output driver
- Operating voltage: 3.8V~28V
- Output current: IO(AVE) = 400mA
- Package: SIP-5L, SOT89-5L
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
the rotor is blocked. Until the blocking is removed,
the motor recovers running normally.
