2-wheeler & 3-wheeler traction drive

Block diagram

Overview

Our integrated circuits and reference designs help you create compact, robust and precise motor control systems for a 2-wheeler or 3-wheeler-traction-drive at a reduced system cost. Robust protection features such as overcurrent shutdown and pre-driver faults are included in these simple and compact solutions.

Design requirements

  • Integrated solutions with built-in protection features
  • Real-time embedded processing solutions
  • Integrated motor control to enable low-latency peripherals
