Three Phase Field Effect

Transistor Pre-driver

The 33937A is a field effect transistor (FET) pre-drivers 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, an

SPI port for device setup and asynchronous reset, enable and

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

and 5.0 V logic level outputs are provided.

Features

• Fully specified from 8.0 to 40 V covers 12 and 24 V automotive

systems

• Extended operating range from 6.0 to 58 V covers 12 and 42 V

systems

• Greater than 1.0 A 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

• Dead time is programmable via the SPI port

• Simultaneous output capability enabled via safe SPI command
