Description

DC1748A-C is a demo board for the LTM2883 I2C uModule isolator with input voltage range 3V to 3.6V. The LTM2883 is a complete galvanic digital uModule isolator. No external components are required. A single 3.3V supply powers both sides of the interface through an integrated, isolated DC/DC converter. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply. The isolated side includes ±12.5V and 5V nominal power supplies, each capable of providing more than 20mA of load current. Each supply may be adjusted from its nominal value using a single external resistor. This device is ideal for systems where the ground loop is broken, allowing for a large common mode voltage range.

Features:

  • UL rated 6 channel logic isolator of 2500Vrms
  • High common mode transient immunity 30KV/us
  • 3.3V operation
  • 1.62V to 5.5V logic supply
  • ±10KV ESD HBM across the isolation barrier
  • Common mode working voltage of 560Vpeak
  • Low current shutdown mode
  • High speed operation 400KHz I2C isolation

Applications:

  • Communications & Networking
  • Industrial
  • Test & Measurement
