DESCRIPTION

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 nominally

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 uninterrupted

communication through large common mode

transients faster than 50kV/μs.
