Description

General part information

LTM2887 Series

The LTM2887 is a complete galvanic digital μModule®(micromodule) isolator. No external components are required. A single 3.3V or 5V 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.Available options are compliant with SPI and I2C (master mode only) specifications.The isolated side includes two 5V nominal power supplies, including programmable current limit, each capable of providing more than 100mA of load current. The supplies may be adjusted from their nominal value using a single external resistor.Coupled inductors and an isolation power transformer provide 2500VRMSof isolation between the input and output logic interface. This device is ideal for systems where the ground loop is broken, allowing for a large common mode voltage range. Communication is uninterrupted for common mode transients greater than 30kV/μs.APPLICATIONSIsolated SPI or I2C InterfacesIndustrial SystemsTest and Measurement EquipmentBreaking Ground Loops
