A89303 - Three-Phase Sensorless Pump Driver

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.

The I2C serial port can be used to
