Anachip AH293W Low voltage hall-effect smart fan motor controller Datasheet

AH293
Low Voltage Hall-Effect Smart Fan Motor Controller
„ Features
„ General Description
- On chip Hall sensor
- Rotor-locked shutdown
- Automatically restart
- Rotor-state detection (RD) output
- Buil t-in Zener protection for output driver
- Operating voltage: 1.8V~5.75 V
- Output current: IO( AVE ) = 400 mA
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.
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
