ISO1050DUBR
Description
Technical Parameters
The ISO1050DUBR isolation interface IC is a reliable choice that meets the ISO11898-2 standard. It provides up to 5000-VRMS (for ISO1050DW) and 2500-VRMS (for ISO1050DUB) isolation capabilities, with fail-safe outputs, low loop delay, 50-kV/μs transient immunity, and bus fault protection. In addition, the ISO1050DUBR features driver-dominant timeout and supports the I/O voltage range of 3.3 V and 5 V microprocessors. Therefore, it is suitable for a variety of applications, provides a high degree of reliability and performance, and is a strong choice in the field of isolated interface ICs.

Description：
The ISO1050 is a galvanically isolated CAN transceiver that meets the specifications of the ISO11898-2 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 5000 VRMS for ISO1050DW and 2500 VRMS for ISO1050DUB. 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.
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). The device is designed for operation in especially harsh environments, and it features cross-wire, overvoltage and loss of ground protection from –27 V to 40 V and overtemperature shutdown, as well as –12V to 12V common-mode range.
The ISO1050 is characterized for operation over the ambient temperature range of –55°C to 105°C.
