A4962 Sensorless BLDC Controller

The A4962 is a three-phase, sensorless, brushless DC (BLDC) motor controller for use with external complementary P-channel and N-channel power MOSFETs and is specifically designed for automotive applications. The A4962 can be used as a stand-alone controller communicating directly with an electronic.

A4962 Features
