LTM2892 2 SPI/Digital or I C Module Isolator Fea T Descrip T n 6-Channel Logic Isolator: 3500V for 1 Minute The LTM 2892 is a complete galvanic digital Module RMS n UL-CSA Recognized File E151738 (micromodule) isolator. No external components are re- n 3V to 5.5V Supply Operation quired. Individual 3V to 5.5V supplies power each side of n No External Components Required the digital isolator. Separate logic supply pins allow easy 2 n SPI/Digital (LTM2892-S) or I C (LTM2892-I) Options interfacing with different logic levels from 1.62V to 5.5V, n High Common Mode Transient Immunity: 50kV/s independent of the main supply. n High Speed Operation: Module options are available with compatibility to SPI n 10MHz Digital Isolation 2 (LTM2892-S) and I C (LTM2892-I), master mode only, n 4MHz/8MHz SPI Isolation specifications. 2 n 400kHz I C Isolation n Coupled inductors provide 3500V of isolation between Operation Up to 125C (H-Grade) RMS n the input and output logic interface. This device is ideal 1.62V to 5.5V Logic Supplies for Flexible Digital Inter- for systems where the ground loop is broken, allowing facing n uninterrupted communication through large common 15kV ESD HBM Across the Isolation Barrier n mode transients faster than 50kV/s.
