Description

General part information

LTM2810 Series

The LTM2810 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 nominally 5V but may be overdriven.Coupled inductors provide 7500VRMSof isolation between the input and output logic interface. This device is ideal for systems with different ground potentials, allowing uninterrupted communication through large common mode transients faster than 50kV/μs.APPLICATIONSEV/HEV SystemsIndustrial and Metering SystemsTest and Measurement EquipmentMedical Equipment
