AH2984 TWO PHASE HALL-EFFECT SMART FAN MOTOR CONTROLLER Description Pin Assignments The AH2984 is a single-chip solution for driving two-coil brushless direct current (BLDC) fans and motors. The device includes a Hall- (Top View) effect sensor, dynamic offset correction and two complementary open-drain output drivers with internal Zener diode protection. It is AH2984 optimized for low start-up voltage. 1 : V DD 2 : DO To help protect the motor coils, the AH2984 provides Rotor Lock Protection which shuts down output drives if rotor lock is detected. 3 : DOB The device automatically re-starts when the rotor lock is removed. Over temperature shutdown provides thermal protection for the 4 : GND 1 2 3 4 device. SIP- 4 The AH2984 is available in SIP4 and SOT89-5 packages. (Top View) Vdd 1 5 NC Features Single-chip solution AH2984 GND 2 GND Operating Voltage: 2.5V to 15V Built-in Hall sensor and input amplifier Rotor Lock Protection (Lock detection, output shutdown and 3 74 DO DOB automatic re-start) SOT89-5 Built-in reverse voltage protection diode Built-in Zener protection for output drivers Average output current up to 500mA Packages: SIP-4 and SOT89-5 Applications Green Molding Compound Two-coil BLDC Cooling Fans Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Low Voltage/ Low Power BLDC Motors Halogen and Antimony Free. Green Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2.

D1 (Zener Diode) and Capacitor C are for power stabilization. Recommended value of C is 1F/ 50V (E-Cap). Diode D2 is optional and helps to protect the device and fan coils from reverse power conditions. The AH2984 also includes an internal reverse blocking diode at V pin.
