The LTM2892CY-I#PBF is a complete galvanic digital μModule® (micromodule) isolator. No external components are required. Individual 3V to 5.5V supplies power each side of the digital isolator. Separate logic supply pins allow easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.
Module options are available with compatibility to SPI (LTM2892-S) and I2C (LTM2892-I), master mode only, specifications.
Coupled inductors provide 3500VRMS of isolation between the input and output logic interface. This device is ideal for systems where the ground loop is broken, allowing uninterrupted communication through large common mode transients faster than 50kV/μs.
