Motor-Expert Suite for BridgeSwitch

Motor-Expert™ Suite is the complete software solution for developing BridgeSwitch integrated half-bridge motor driver designs.

The Motor-Expert Suite bundle includes:

  • Motor-Expert Motor Control Configuration and Diagnostics Tool
  • BridgeSwitch Single-Phase BLDC Fan Motor Control Code Library
  • BridgeSwitch Three-Phase Sensorless FOC Code Library using Integrated Phase Current (IPH)


Motor-Expert is an application designed to aid the configuration, tuning, and diagnostic of Power Integrations' Brushless Motor development kits. It provides a graphic user interface (GUI) allowing easy manipulation of input parameters, as well as a terminal emulator for interacting with the motor controller in serial mode. In addition, a motion scope feature displays linear graphs of important controller variables that can be viewed in real time.

BridgeSwitch Code Libraries

The code libraries for single- and three-phase motor control are designed to be a starting point for creating firmware to control BridgeSwitch-based inverter technology. They allow real-time adjustment of motor speed and torque via the Motor-Expert GUI. The new code is MISRA C-compliant (Motor Industry Software Reliability Association), portable, modular and allows the user to modify any of the software layers.
