AH287 HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Features • • • • • • • • • On Chip Hall Sensor Rotor-Locked Shutdown Automatically Restart Built-in Zener Protection for Output Driver Operating Voltage: 3.8V~28V Output Current: IO(AVE) = 400mA Lead Free Packages: SIP-4L and SOT89-5L (Note 1) SIP-4L and SOT89-5L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/ RoHS Compliant (Note 2) General Description AH287 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain drivers for motor’s coil driving, automatic lock shutdown and restart function relatively. 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 24V D2 287 D1 L2 L1 1 2 3 4 GND DOB D3 C1 DO 48V 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 Brush-Less DC Fan AH287 Rev. 10 DS31042 1 of 11 www.diodes.com APRIL 2010 © Diodes Incorporated AH287 HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Ordering Information AH 287 - X X - X Package P : SIP-4L Y : SOT89-5L Package Code P P Y Y Packaging (Note 3) SIP-4L SIP-4L SOT89-5L SOT89-5L Lead Free L : Lead Free (Note 1) G : Green Bulk Part Number Quantity Suffix 1000 -B 1000 -B NA NA NA NA Packing B : Bulk 13 : Tape & Reel 13” Tape and Reel Part Number Quantity Suffix NA NA NA NA 2500/Tape & Reel -13 2500/Tape & Reel -13 Device AH287-PL-B AH287-PG-B AH287-YL-13 AH287-YG-13 Notes: 1.
