Description

The DRV3256-Q1 family of devices are highly-integrated three phase gate driver s 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.
