MC33937: 3-Phase Field Effect Transistor Pre-driver

The NXP^® MC33937A 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 asynchronous reset, enable and interrupt signals
• Both 5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are provided
• Processor Expert^® component for MC33937 enables rapid embedded application development
