Advance Information

Three-Phase Field Effect

Transistor Pre-Driver

33927

The 33927 is a Field Effect Transistor (FET) pre-driver designed for

three-phase motor control and similar applications. The integrated

circuit (IC) uses SMARTMOS™ technology.

FET PRE-DRIVER

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, a SPI

port for device setup and asynchronous reset, enable and interrupt

signals. Both 5.0V and 3.0V logic level inputs are accepted and 5.0V

logic level outputs are provided.
