A4963 Overview
The A4963 is a three-phase, sensorless, brushless DC (BLDC) motor controller for use with external plementary P-channel and N-channel power MOSFETs. The A4963 can be used as a stand-alone controller municating directly with an electronic control unit (ECU) or it can be used in a close-coupled system with a local microcontroller (MCU). The motor is driven using block mutation (trapezoidal drive) where phase mutation...
