LTM2810

7.5kV SPI/Digital or I C µModule

RMS

Isolator with Transformer Driver

FEATURES

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.

6-Channel Logic Isolator: 7500V

for 1 Minute

RMS

16.2mm Creepage

CSA (IEC/UL) Approved, File #255632

3V to 5.5V Supply Operation

Transformer Driver with Integrated Isolated Side LDO

SPI/Digital (LTM2810-S) or I C (LTM2810-I) Options

High Common Mode Transient Immunity: 50kV/μs

High Speed Operation:

Module options are available with compatibility to SPI

(LTM2810-S) and I C (LTM2810-I), master mode only,

10MHz Digital Isolation

specifications.

4MHz/8MHz SPI Isolation

400kHz I C Isolation

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.

Operation Up to 125°C (H-Grade)

1.62V to 5.5V Logic Supplies for Flexible Digital

Interfacing

25kV ESD HBM Across the Isolation Barrier

Coupled inductors provide 7500V_RMSof 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.

Maximum Continuous Working Voltage:1kV , 1.6kV

RMS

Low Current Shutdown Mode (<10µA)
