MC34937APEKR2

The 34937A is a field effect transistor (FET) pre-driver designed for three-phase motor control and similar applications. The integrated circuit (IC) uses SMARTMOS technology. The IC contains three high side FET pre-drivers and three low side FET pre-drivers. 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 fault detection, an asynchronous reset, an interrupt and two enable signals. Both 5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are provided.
