Reference design for a low-cost improvement and analysis platform focused to drive a three-phase Everlasting Magnet Synchronous (PMSM) or Brushless DC (BLDC) automotive cooling fan motor.
An automotive cooling fan is used to chill the engine in an ICE car or energy electronics and motors in an electrical car (EV). The fan pulls air via the radiator and coolant system, serving to to dissipate warmth and preserve the engine or motor drives on the correct working temperature. That is essential for the correct functioning and longevity of the engine.
The automotive cooling fan reference design from Microchip is a low-cost improvement and analysis platform focused to drive a three-phase Everlasting Magnet Synchronous or Brushless DC Automotive Cooling fan motor, which might be networked by way of LIN. This design relies on the Microchip dsPIC33CDVL64MC106 and a motor management System in Bundle (SiP). The SiP accommodates a dsPIC33CK64MC105 DSC, a MCP8021 three-phase MOSFET gate driver with LDOs and an ATA663211 LIN transceiver.
The reference design has been examined by Microchip. To simplify the designing course of, TI has offered the entire set of Design Assets together with schematics, invoice of supplies, PCB structure, and take a look at information, which might be downloaded from right here.
Key options of the Reference Design:
• Three-Section Motor Management Energy Stage
• DC Bus present suggestions for overcurrent safety and to implement a single shunt present reconstruction algorithm
• DC Bus voltage suggestions for overvoltage safety
• Section voltage suggestions to implement sensorless trapezoidal management or flying begin
• ICSP™ header for interfacing to a Microchip Programmer/Debugger
• UART Communication Header
• LIN interface (LIN transceiver is a part of dsPIC33CDVL64MC106)
