Features

  • Real-time, variable gate drive strength features enable improved system efficiency by minimizing the SiC switching power losses and the accurate bias supply minimizes conductive losses
  • Isolated gate drivers, bias supply modules, and highly integrated voltage sensing devices for the direct connection to the high-voltage source significantly reduce PCB area
  • High-performance microcontroller (MCU) with three C29 real-time digital signal processor (DSP) cores enable motor control loop with < 2µs to help minimize torque ripple and to provide smooth speed and torque current profiles to the traction motor
  • A system-on-module design with 3 × 120 high-speed, high-density connectors supports higher pin demands for MCU evaluation
  • UCC5880-Q1 and F29H859TU-Q1 are Functional Safety-Compliant devices
  • Enhanced system-reliability rated with reinforced capacitive isolation technology and early failure detection
