2.3.2 DRV3255-Q1

The DRV3255-Q1 device is a highly-integrated three-phase gate driver for 48-V automotive motor drive applications. The device is specifically designed to support high-power motor drive applications by providing 3.5-A peak source and 4.5-A peak sink gate drive currents, and 90-V MOSFET transient overvoltage 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.
