MC33937 - NXP

MC33937 Three phase field effect transistor pre-driver

The 33937A is a field effect transistor (FET) predriver designed for three phase motor control and similar applications. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified. The IC contains three high-side FET predrivers and three low-side FET predrivers. Three external bootstrap capacitors provide gate char.
