MTRCKTSBN5643L Fact Sheet

Automotive Motor Control Development Solutions
3-Phase Sensorless BLDC Kit
with Qorivva MPC5643L MCU
Target Automotive
Applications
• Air conditioning units
• Automotive drives
•Compressors
•Fans
• Motor control
•Pumps
Overview
This application is designed for the Qorivva MPC5643L controller board with an
encoder/resolver interface and 3-phase BLDC/PMSM low-voltage power stage
equipped with a 3-phase MC33937A pre-driver. Beside the main control loop, the
DC bus current and DC bus and phase voltages are monitored during the control
process for overvoltage, undervoltrage and overcurrent drive protection.
Freescale offers a broad portfolio of automotive MCUs, MPUs analog integrated
circuits and sensor solutions, along with extensive enablement and technical
support, empowering you to create the next breakthrough automotive designs for
powertrain, body, chassis and safety, infotainment and telematics, and in-vehicle
networking applications.
