特長
 
  • Control Logic
    - Ensures safe power−up sequence and the correct reaction to different supply conditions
    - Controls mode transitions including the power management and wakeup treatment − bus wakeups, local wakeups (via WU pin) and cyclic wakeups (through the on−chip timer)
    - Generates reset and interrupt requests
  • Serial Peripheral Interface
    - Operates with 16−bit frames
    - Ensures communication with the ECU’s microcontroller unit
    - Mode settings, chip status feedback and watchdog are accessible through eight twelve−bits registers
  • 5 V VOUT Supply from a DC/DC Converter
    - Can deliver up to 500 mA with accuracy of ±2%
    - Supplies typically the ECU’s microcontroller
  • 5 V VOUT2 Low−drop Output Regulator
    - Can supply external loads – e.g. sensors
    - Controlled by SPI and the state machine
    - Protected against short to the car battery
  • 11 V (NCV7471B) or 6.5 V (NCV7471C) V_MID Supply from a DC/DC Converter
  • A High−speed CAN/CANFD Transceiver
    - ISO11898−2: 2016 Compliant
    - Communication speed up to 1 Mbps
    - Specification for loop delay symmetry up to 2 Mbps
    - TxD dominant time−out protection
  • Two LIN Transceivers
    - ISO17987−4, LIN2.X and J2602 compliant
    - TxD dominant time−out protection
  • Wakeup Input WU
    - Edge−sensitive high−voltage input
    - Can be used as a wake−up source or as a logical input polled through SPI
  • Protection and Monitoring Functions
    - Monitoring of the main supply through the V_MID point
    - Monitoring of VOUT supply output with programmable threshold
    - VOUT2 supply diagnosis through SPI and interrupt
    - Thermal warning and thermal shutdown protection
    - Programmable watchdog monitoring the ECU software
  • NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
  • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
