MC33927

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.com 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 command Pb-Free Packaging Designated by Suffix Code EK VBAT 33927 FET PRE-DRIVER EK SUFFIX (Pb-FREE) 98ASA99334D 54-PIN SOICW-EP ORDERING INFORMATION Device MCZ33927EK/R2 Temperature Range (TA) -40°C to 125°C Package 54 SOICW-EP 33927 VPUMP PUMP VPWR VLS VDD VSS 3 3 3 VBAT PA_HS_G PB_HS_G PC_HS_G PA_HS_S P...
