Overview
...start - Rotor-state detection (RD) output - Buil t-in Zener protection for output driver - Operating voltage: 3.
8V~20 V - Output current: IO(AVE) = 500mA for SIP-5/SOT89-5 - Output current: IO(AVE) = 400mA for SOT23-5 - Package: SIP-5L, SOT23-5L, SOT89-5L „ General Description AH286 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.
To avoid coil burning, rotor-lock shutdown detection circuit shut down the output driver if the rotor is blocked and then the automa...
