DRV3211-Q1 Overview
The DRV3211-Q1 device is a field effect transistor (FET) pre-driver designed for 3-phase motor control and its application such as an oil pump or a water pump. It is equipped with three high-side pre-FET drivers and three low-side drivers which are controlled by an external microcontroller (MCU). The power for the high side is supplied by a charge pump and no bootstrap cap is needed.
