2.0, 8/2007 Three-Phase Field Effect Transistor Pre-Driver 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.

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
