1 General description
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 charge to the high-side FETs.
The IC interfaces to a MCU via six direct input control signals, an SPI port for device setup and asynchronous reset, enable and interrupt signals. Both 5.0 and 3.0 V logic level inputs...
