Integrated 3-phase 48-V automotive Gate Driver Unit (GDU) with 4.5-A peak sink gate drive current

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.
