AH2984
TWO PHASE HALL-EFFECT SMART FAN MOTOR CONTROLLER
Description
The AH2984 is a single-chip solution for driving two-coil brushless
direct current (BLDC) fans and motors. The device includes a Hall-
effect sensor, dynamic offset correction and two complementary
open-drain output drivers with internal Zener diode protection. It is
optimized for low start-up voltage.
To help protect the motor coils, the AH2984 provides Rotor Lock
Protection which shuts down output drives if rotor lock is detected.
The device automatically re-starts when the rotor lock is removed.
