A89303 - Three-Phase Sensorless Pump Driver

General Description

The A89303 three-phase motor driver incorporates sensorless drive intended to drive low power automotive BLDC motors.

A trapezoidal drive algorithm is implemented to minimize time to ramp up to maximum speed.

The device can be operated by PWM duty or I2C interface.

Key Features

  • AEC-Q100 qualified.
  • I2C serial port control.
  • Fast startup features.
  • Trapezoidal drive.
  • Sensorless (no Hall sensors required).
  • Low RDS(ON) power MOSFETs.
  • FG speed output.
  • Lock detection.
  • Soft start.
  • Overcurrent protection.
  • Overvoltage protection.
  • Diagnostic outputs.
  • Small form factor automotive pump.
