Features

General

  • ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver
  • Loop delay symmetry timing enables reliable communication at data rates up to 2 Mbit/s in the CAN FD fast phase
  • Autonomous bus biasing according to ISO 11898-6
  • Fully integrated 5 V/100 mA low-drop voltage regulator for 5 V microcontroller supply (V1)
  • Bus connections are truly floating when power to pin BAT is off

Designed for Automotive Applications

  • ±8 kV ElectroStatic Discharge (ESD) protection, according to the Human Body Model (HBM) on the CAN bus pins
  • ±6 kV ESD protection, according to IEC 61000-4-2 on the CAN bus pins and on pin BAT
  • CAN bus pins short-circuit proof to ±58 V
  • Battery and CAN bus pins protected against automotive transients according to ISO 7637-3
  • Very low quiescent current in Standby mode with full wake-up capability
  • Leadless HVSON14 package (3.0 mm x 4.5 mm) with improved Automated Optical Inspection (AOI) capability and low thermal resistance
  • Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)

Low-drop voltage regulator for 5 V microcontroller supply (V1)

  • 5 V nominal output; ±2 % accuracy
  • 100 mA output current capability
  • Current limiting above 150 mA
  • On-resistance of 5 Ω (max)
  • Support for microcontroller RAM retention down to a battery voltage of 2 V
  • Undervoltage reset at 90 % of nominal value
  • Excellent transient response with a 4.7 μF ceramic output capacitor
  • Short-circuit to GND/overload protection on pin V1

Power Management

  • Standby mode featuring very low supply current; voltage V1 remains active to maintain the supply to the microcontroller
  • Remote wake-up capability via standard CAN wake-up pattern

System Control and Diagnostic Features

  • Mode control via pin STBN
  • Overtemperature shutdown
  • Bidirectional reset pin
