AH283 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: 10V~20 V, driver start up: 8V (minimum) - Output current: IO( AVE ) = 300 mA AH283 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. 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 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 Descriptions Pin Configuration Symbol RD VCC DO DOB GND ( Front View ) 283 1 : RD 2 : VCC 3 : DO Description Rotor-state detection Input power Output pin Output pin Ground 4 : DOB 5 : GND 1 2 3 4 5 SIP-5L VCC 1 GND 2 5 RD AH283 DO 3 74 DOB SOT89-5L Ordering Information AH283 X - X X X Wafer Body Package Lead Packing Blank or A~Z : if necessary to specify P: SIP-5L Y: SOT89-5L L : Lead Free Blank: Normal Blank : Tube or Bulk A : Tape & Reel This datasheet contains new product information.
