MC33927 Datasheet Three-phase Field Effect Transistor Pre-driver

Manufacturer: Freescale Semiconductor (now NXP Semiconductors)

Overview: Freescale Semiconductor Advance Information Document Number: MC33927 Rev. 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 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. www.DataSheet4U.

Key Features

  • Fully specified from 8.0V to 40V covers 12V and 24V automotive systems.
  • Extended operating range from 6.0V to 58V covers 12V and 42V systems.
  • 1.0A gate drive capability with protection.
  • Protection against reverse charge injection from CGD and CGS of external FETs.
  • Includes a charge pump to support full FET drive at low battery voltages.
  • Deadtime is programmable via the SPI port.
  • Simultaneous output capability enabled via safe SPI co.
