AH287-YL-13

PART OBSOLETE - NO ALTERNATE PART AH287 OBSOLETE – PART DISCONTINUED HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Features 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.   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) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ 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 24V L2 287 D1 1 2 3 L1 4 GND DOB D3 C1 48V DO 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 Document number: DS31042 Rev. 11 - 4 1 of 11 www.diodes.com March 2020 © Diodes Incorporated AH287 HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Ordering Information OBSOLETE – PART DISCONTINU ED AH 287 - X X - X Package P : SIP-4L Y : SOT89-5L Device Package Code Packaging (Note 3) P P Y Y SIP-4L SIP-4L SOT89-5L SOT89-5L AH287-PL-B AH287-PG-B AH287-YL-13 AH287-YG-13 Notes: Lead Free Packing L : Lead Free (Note 1) G : Green B : Bulk 13 : Tape & Reel Bulk Part Number Quantity Suffix 1000 -B 1000 -B NA NA NA NA 13” Tape and Reel Part Number Quantity Suffix NA NA NA NA 2500/Tape & Reel -13 2500/Tape & Reel -13 1.
