Description
The AH2984 is a single-chip solution for driving two-coilbrushless 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. Over temperature shutdown provides thermal protection for the device.
Application
- Two-coil BLDC Cooling Fans
- Low Voltage/ Low Power BLDC Motors
