The LTM2810 µModule isolators are suitable for test and measurement equipment, medical equipment, electric vehicle (EV) and hybrid electric vehicle (HEV) systems, industrial applications, and metering systems.
The Analog Devices LTM2810 µModule isolators, available from Mouser Electronics, feature separate logic supply pins, supporting easy interfacing with different logic levels ranging from 1.6 V to 5.5 V. The devices coupled isolators are powered on each side by 3 V to 5.5 V supplies and provide 7.5 kVRMS 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 50 kV/µs.
The LTM2810 µModule isolators feature an integrated transformer driver on the logic side and a low-dropout (LDO) regulator on the isolated side, regulating 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 400 kHz I2C isolation, 4 MHz / 8 MHz SPI isolation, and 10 MHz digital isolation. The LTM2810 µModule isolators feature 16.2 mm creepage and offer a maximum continuous working voltage of 1 kVRMS and 1.6 kVDC.
