AH5772 - SINGLE PHASE MOTOR DRIVER

Description

The AH5772 is a single chip solution for driving single-coil brushless direct current (BLDC) fans and motors.

The integrated full-bridge driver output stage uses soft switching to minimize audible switching noise and electromagnetic interference (EMI) providing a low noise solution.

Features

  • Supports Single-phase Full Wave BLDC Fan/Motor Drive.
  • Wide Operating Voltage Range: 2.4V to 18V.
  • Built-in High Sensitivity Hall Effect Sensor.
  • Very Low Temperature and Voltage Coefficient of the Magnetic Operating Switch Points.
  • Built-in H-Bridge with Low RDSON Resistance.
  • Soft Switching for Low Noise DC Fan Motor.

NEW PRODUCT AH5772 SINGLE PHASE MOTOR DRIVER WITH INTERNAL HALL EFFECT LATCH SENSOR Description The AH5772 is a single chip solution for driving single-coil brushless direct current (BLDC) fans and motors. The integrated full-bridge driver output stage uses soft switching to minimize audible switching noise and electromagnetic interference (EMI) providing a low noise solution. Pin Assignments (Front View) To simplify system circuit and minimize external components, the device integrates a stable high sensitivity Hall-Effect sensor, voltage and temperature compensated internal references, amplifiers and the output H-bridge power switches with low RDSON. To help protect the motor coil, the AH5772 provides Rotor Lock Protection which shuts down the output drive if rotor lock is detected.
