AH2985 - Diodes

AH2985 TWO PHASE HALL-EFFECT SMART FAN MOTOR CONTROLLER

The AH2985 is a single-chip solution for driving two-coil brushless direct current (BLDC) fans and motors. The device includes a Halleffect 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 AH2985 provides Rotor.
