AH282A-PA

AH282 Hall-Effect Smart Fan Motor Controller Features - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Frequency generator (FG) output - Buil t-in Zener protection for output driver - Operating voltage: 10V~20V, driver start up: 8V (minimum) - Output current: IO( AVE ) = 300 mA General Description AH282 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-collector transistors as motor coil drivers, automatic lock current shutdown, and recovery protections. Additional, 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. This function repeats while the rotor is blocked. Until the blocking is removed, the motor recovers running normally. - Package: SIP-5L, SOT89-5L Pin Configuration 282 ( Front View ) 1 : FG 2 : VCC 3 : DO 4 : DOB 5 : GND 123 45 Pin Descriptions Symbol Description FG VCC DO DOB GND Frequency generation Input power Output pin Output pin Ground SIP-5L VCC 1 GND 2 DO 3 SOT89-5L AH282 7 DOB 4 5 FG Ordering Information AH282 X - X X X Wafer Body Blank or A~Z : if necessary to specify Package P: SIP-5L Y: SOT89-5L Lead L : Lead Free Blank: Normal Packing Blank : Tube or Bulk A : Tape & Reel This datasheet contains new product information.
