3 Description

The DRV3256-Q1 family of devices are highlyintegrated

three phase gate drivers for 48-V

automotive motor drive applications. These devices

are specifically designed to support high-power motor

drive applications by providing 2-A peak source

and 2.5-A peak sink gate drive currents, and 90-V

MOSFET transient over voltage support. A highly

efficient bootstrap architecture is used to minimize

power losses and self-heating of the gate drivers. A

charge pump allows for the gate drivers to support

100 PWM duty cycle control.

A wide range of diagnostics, monitoring, and

protection features supports a robust motor drive

system design. A highly configurable Active Short

Circuit (ASC) function which enables selected

external MOSFETs is integrated to achieve the fast

response to system faults and to eliminate the needs

of external components.

Three or single low-side current shunt amplifiers are

optionally provided to support resistor based low-side

current sensing.
