Texas Instruments LM5160DNTR | Demoboard TIDA-00300

Description

This reference design provides a simple means through which to isolate I2C or SPI type communication lines. This is often required in Grid Infrastructure applications such as, protertion relays and circuit breakers, where high voltages are involved. This reference design provides the complete solution in which, both power isolation and signal isolation is handled
