A4963 Sensorless BLDC Controller

The A4963 is a three-phase, sensorless, brushless DC (BLDC) motor controller for use with external complementary P-channel and N-channel power MOSFETs. The A4963 can be used as a stand-alone controller communicating directly with an electronic control unit (ECU) or it can be used in a close-coupled .

A4963 Features

* Three-phase sensorless BLDC motor control FET driver

* Logic level P-N gate drive (P high-side, N low-side)

* 4.2 to 50 V supply range

* Simple block commutation for maximum torque

* Sensorless (bemf sensing) startup and commutation

* Programmable op
