The DRV325x-Q1 family of devices are integrated 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 3.5-A peak source and 4.5-A peak sink gate drive currents, 90-V MOSFET transient over voltage support, and using a highly efficient bootstrap architecture that minimizes 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 achive the fast response to system faults and to eliminate the needs of external components.

Three low-side current shunt amplifiers are optionally provided (DRV3256-Q1) to support resistor based low-side current sensing.
