µModule isolators offer 7.5kV isolation for industrial and automotive systems

21-05-2019 | Analog Devices | Power

Mouser now offers the Power by Linear LTM2810 µModule isolators from Analog Devices. Giving up to 7.5kVRMS of isolation, the isolators are ideal for test and measurement equipment, medical equipment, EV and HEV systems, industrial applications, and metering systems.

The µModule isolators provide separate logic supply pins, supporting easy interfacing with different logic levels ranging from 1.6V to 5.5V. The devices coupled isolators are powered on each side by 3V to 5.5V supplies and give 7.5kVRMS of isolation for one minute between the input and output logic interface. Ideal for systems with various ground potentials, the µModule isolators allow uninterrupted communication through large common mode transients faster than 50kV/µs.


The µModule isolators offer an integrated transformer driver on the logic side and a LDO regulator on the isolated side, regulating the rectified transformer output. The complete galvanic digital isolators need no external components and are offered in SPI and I2C (with master mode-only support) compatible variants. The devices boast high-speed operation, with 400kHz I2C isolation, 4MHz/8MHz SPI isolation, and 10MHz digital isolation. The isolators feature 16.2mm creepage and provide a maximum continuous working voltage of 1kVRMS and 1.6kVDC.
