ISO1050 - Isolated CAN Transceiver

Texas Instruments' ISO1050 simplifies system design and layout

ISO1050 - Isolated CAN Transceiver 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.
