Technical and Functional Specifications

Enablement Kit (EV-INVERTERHDBT):

  • Contains two PCB boards and software (IGBT module, link capacitor, bus bar and cooling fixture are not included and to be provided by the customer) to drive a three-phase motor to enable quick development of an in-house inverter design using NXP inverter control solution
  • Plug and play bus bar connectors for conveniently accessing the P6 IGBT power module output terminals
  • Software to allow for system configuration and basic motor control of a three-phase inverter for driving a permanent magnetic synchronous motor (PMSM) or induction motor

MCU Control Board
(EV-CONTROLEVMHD):

  • The MPC5775E is a 32-bit Power Architecture© dual core ASIL D MCU targeted for motor control offering performance up to 264MHz/core, CSE security, eTPU timers, software resolver and a highly scalable solution
  • Robust FS65xx system basis chip (SBC) providing power to the MCU with low voltage side monitoring and protection
  • The TJA1051 transceiver for high-speed CAN differential transmit and receive physical interface to the MCU. As an alternative communication protocol, the TJA1100HNZ automotive ethernet PHY chip with 100BASE-TI single-port PHY is also offered
  • Interface connector is a 23-pin connector for motor control inputs
  • Three LEM current sensors are incorporated on the board providing +/- 900 Amp measurement range

Driver Control Board for HD Module
(EV-POWEREVBHDBT):

  • The board is designed to be compatible with an industrial standard P6 IGBT Power module footprint, like with onsemi VE-Trac and Infineon HybridPACK
  • The board features GD3160 advanced single-channel gate driver for IGBTs and SiC MOSFETs with integrated galvanic isolation and low on-resistance drive transistors to provide high charging and discharging current, low dynamic saturation voltage and rail-to-rail gate voltage control
  • The board autonomously manages and reports severe faults, status via SPI interface, INTA and INTB pin
  • Gate voltage is supplied via isolated transformers and a fly back controller

Enablement Software which features:

  • NXP SDK with production ready SPCE/CMMI Class B and MISRA 2012 compliant Low level SDK device drivers
  • Special function drivers for SW resolver digital converter (RDC) for motor position detection without need for additional HW resolver and precise PWM SW implementation on eTPUs for gate driver controls
  • Advanced AMMCLIB optimized software libraries for precise motor drive control
  • Freemaster and Motor Control Application Tuning tool (MCAT) is provided as a graphical user Interface for operating and monitoring the inverter platform

Functional Safety

  • Targeting ASIL C/D compliance with small, compact 9 IC system footprint
  • Functional safety requirements targeting ASIL C/D integrated into system level HW design and safety SW implementation
  • Example safety checker-reaction library implemented using safety runtime framework (SRF) on the enablement software
  • Optional add-on safety package for ICP 2.0 EV-INVERTERHDBT kit includes detailed Safety goals, Hazard analysis and risk assessment (HARA), function safety report (FSR), technical safety report (TSR) for HW and SW design, SRF source code and system safety libraries (to be purchased separately)
  • NXP functional safety consultation service to enable customers to meet their target safety concepts (contact your local sales to know more)
  • Highly-active SafeAssure® NDA group for Functional Safety expert support

Collaterals

  • Inverter control hardware design package (schematics, PCB layout, Gerber files)
  • Hardware enablement kit including control and driver boards
  • Enablement kit user guide
  • System design guide application note
  • Inverter application system enablement software including service layer, AMMCLIB, eTPU function set, low-level SDK device drivers and Freemaster/ MCAT debug support
  • Freemaster GUI and Freemaster/MCAT user guide
  • Inverter enablement software user manual
  • NXP device datasheets
  • NXP device functional safety documents
  • NXP standalone device software drivers
