In stock at distributor Mouser Electronics are the LTM2810 µModule isolators from Analog Devices. Offering up to 7.5kVRMS of isolation, the isolators are suitable for test and measurement equipment, medical equipment, electric vehicle (EV) and hybrid electric vehicle (HEV) systems, industrial applications, and metering systems.
Featuring separate logic supply pins, the isolators support 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 provide 7.5kVRMS of isolation for one minute between the input and output logic interface. Ideal for systems with different ground potentials, the LTM2810 µModule isolators enable uninterrupted communication through large common mode transients faster than 50kV/µs.
An integrated transformer driver on the logic side and a low-dropout (LDO) regulator on the isolated side, regulate the rectified transformer output. The complete galvanic digital isolators require no external components and are available 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. They feature 16.2mm creepage and offer a maximum continuous working voltage of 1kVRMS and 1.6kVDC.
