ISO1050 - Isolated CAN Transceiver


Digi-Key and Texas Instruments Introduce ISO1050 - Simplifying System Design and Layout

Texas Instruments' ISO1050 is a galvanically isolated CAN transceiver that meets or exceeds the specifications of the ISO 11898 standard. The device has the logic input and output buffers separated by a silicon oxide (SiO2) insulation barrier that provides galvanic isolation of up to 4000 VPEAK. Used in conjunction with isolated power supplies, the device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.

Overview

As a CAN transceiver, the device provides differential transmit capability to the bus and differential receive capability to a CAN controller at signaling rates up to 1 megabit per second (Mbps). Designed for operation in especially harsh environments, the device features cross-wire, overvoltage and loss of ground protection from –27V to 40V and overtemperature shut-down, as well as a –12V to 12V common-mode range.

Benefits of the ISO1050:
  •   Fully compliant to CAN Standard
  •   High Speed Isolation allows longer buses
  •   Network will not interfere with other devices
  •   Proven Reliability of SiO2 Insulation, Stable over Time, Temperature & Moisture
      –   Life Span > 25 years @ 125°C
