AH289-YL-13

NOT RECOMMENDED FOR NEW DESIGN – AH289 NO ALTERNATE PART HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER General Description Features • • • • • • • • • • On Chip Hall Sensor Rotor-Locked Shutdown Automatically Restart Rotor-State Detection (RD) Output Built-in Zener Protection for Output Driver Operating Voltage: 3.8V~28V Output Current: IO (AVE) = 400mA Lead Free Package: SOT89-5L (Note 1) SOT89-5L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/ RoHS Compliant (Note 2) AH289 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain transistors for motors coil driving, an automatic lock current shutdown, and recovery protection. In addition, the Rotor-State Detection (RD) output is for Rotor-State Detection. Rotor-lock shutdown detection circuit turns off the output driver when the rotor is blocked to avoid coil overheat. Then, the automatic recovery circuit will restart the motor. These protected actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers and runs normally. Typical Application Circuit D2 Vdd (24V) D1 R pu 4 5 Coil2 289 RD 1 D3 2 C1 Coil1 3 48V GND * Rpu : typical 10 Kohm 48V Note: The optional Capacitor C1 and Diode D3 are for power stabilization. C1 is recommended to be E-Cap., luF/25V; D3 is recommended to be Zener Diode, VZ =27V. Which C1and D3 value need to be fine tuned to optimize design for different coils and power suppliers. 24V DC Brush-Less Fan with RD Output Function AH289 Rev. 12-3 DS31052 1 of 9 www.diodes.com January 2021 © Diodes Incorporated AH289 HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Ordering Information AH289 - Y L - 13 Package Lead Free Packing Y : SOT89-5L L : Lead Free (Note 1) G : Green 13 : Tape & Reel Package Code Y Y Device AH289-YL-13 AH289-YG-13 Notes: 13” Tape and Reel Quantity Part Number Suffix 2500/Tape & Reel -13 2500/Tape & Reel -13 Packaging (Note 3) SOT89-5L SOT89-5L 1.
