1 / 30 page  LTM2810 1 Rev. A For more information www.analog.com TYPICAL APPLICATION FEATURES DESCRIPTION 7.5kVRMS SPI/Digital or I2C µModule Isolator with Transformer Driver The LTM®2810 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 (LTM2810-S) and I2C (LTM2810-I), master mode only, specifications. The module includes an integrated transformer driver on the logic side and an LDO on the isolated side to regulate the rectified transformer output. The LDO output is nomi- nally 5V but may be overdriven. Coupled inductors provide 7500VRMS of isolation between the input and output logic interface. This device is ideal for systems with different ground potentials, allowing unin- terrupted communication through large common mode transients faster than 50kV/μs.
