CAN Transceiver with Fast Loop Times for Highly Loaded Networks and Features for Functional Safety - SN65HVD257

SN65HVD257 (ACTIVE)

CAN Transceiver with Fast Loop Times for Highly Loaded Networks and Features for Functional Safety

Recommended alternative parts

  • ISO1050  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Combines Isolation and CAN, but has different feature set than the SN65HVD257

Description

This CAN transceiver meets the ISO1189-2 High Speed CAN (Controller Area Network) Physical Layer standard. It is designed for data rates in excess of 1 Mbps for CAN in short networks, and enhanced timing margin and higher data rates in long and highly-loaded networks. The device provides many protection features to enhance device and CAN-network robustness. The SN65HVD257 adds additional features, allowing easy design of redundant and multi-topology networks with fault indication for higher levels of functional safety in the CAN system.

Features

  • Meets the Requirements of ISO11898-2
  • ‘Turbo’ CAN:
    • Short and Symmetrical Propagation Delay Times
      and Fast Loop Times for Enhanced Timing Margin
    • Higher Data Rates in CAN Networks
  • I/O Voltage Range Supports 3.3V and 5V MCUs
  • Ideal Passive Behavior When Unpowered
    • Bus and Logic Pins are High Impedance (no load)
    • Power Up/Down With Glitch Free Operation On Bus
  • Protection Features
    • HBM ESD Protection Exceeds ±12kV
    • Bus Fault Protection –27V to 40V
    • Undervoltage Protection on Supply Pins
    • Driver Dominant Time Out (TXD DTO)
    • SN65HVD257: Receiver Dominant Time Out (RXD DTO)
    • SN65HVD257: FAULT Output Pin
    • Thermal Shutdown Protection
  • Characterized for –40°C to 125°C Operation
