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.
Document Number: MC33927
Rev. 2.0, 8/2007
33927
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.
