A89307 Automotive FOC BLDC Motor Controller

The A89307 is a 3-phase, sensorless, brushless DC (BLDC) motor driver (gate driver) that can operate from 5.5 to 50 V. A field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise performance. Constant torque and constant power mode are provided as w.
