AH292 Low Voltage Hall-Effect Smart Fan Motor Controller Features General Description - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Frequency generator (FG) output - Buil t-in Zener protection for output driver - Operating voltage: 1.8V~5.75 V - Output current: IO( AVE ) = 400 mA AH292 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, frequency generator (FG) output is for speed detection relatively. 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 Pin Configuration 292 DOB 4 FG 5 ( Front View ) VCC 1 1 : FG 292 2 : VCC 4 : DOB 1 2 3 VCC GND DO SOT23-5 1 2 3 4 5 SIP-5L AH292 GND 2 3 : DO 5 : GND 5 FG DO 3 74 DOB SOT89-5L Pin Descriptions Symbol FG VCC DO DOB GND Description Frequency generation Input power Output pin Output pin Ground Ordering Information AH292 X - X X X Wafer Body Package Lead Packing Blank or A~Z : if necessary to specify P: SIP-5L W: SOT23-5L Y: SOT89-5L L : Lead Free Blank: Normal Blank : Tube or Bulk A : Tape & Reel This datasheet contains new product information.
