Enablement Kit
(EV-INVERTER)

  • Contains four PCB’s, cabling and basic three phase software to enable quick development of your in-house inverter design using a complete NXP solution.
  • Software will be provided to allow for system configuration and basic control of a three-phase inverter for driving a permanent magnetic synchronous motor (PMSM) or induction motor.

MCU Control Board
(EV-CONTROLEVM)

  • For each of the boards included in the Enablement Kit, hardware schematics, PCB layouts and gerber files will be available on the NXP website for download.
  • This board contains three key NXP integrated circuits. The MPC5775E is a 32-bit Power Architecture© dual core MCU with lock step offering performance up to 264 MHz/core, CSE security, eTPU timers and a highly scalable solution. The FS6500 system basis chip (SBC) providing power to the MCU optimizing energy consumption and providing low voltage side monitoring and protection. The TJA1042 transceiver for high-speed CAN applications in the automotive industry providing the differential transmit and receive capability to the MPC5775E and a CAN protocol controller.

Driver Control Board
(EV-POWEREVB)

  • This board is designed for the Fuji M653 IGBT 6-pack inverter module. It features the GD3100 advanced single-channel gate driver for IGBTs and SiC MOSFETs with integrated galvanic isolation and low on-resistance drive transistors. Providing high charging and discharging current, low dynamic saturation voltage and rail-to-rail gate voltage control. Autonomously manages severe faults and reports faults and status via INTB pin and an SPI interface. Gate voltage is supplied via isolated transformers and a flyback controller.

Sensor Board
