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 2500V_RMS of 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.

Product Details

Demonstration circuit 1791A is a serial peripheral interface bus (SPI) or inter-IC bus (I²C) μModule isolator with dual adjustable 5V regulators featuring the LTM2887. The demo circuit features an EMI optimized circuit configuration and printed circuit board layout. All components are integrated into the μModule isolator. The demo circuit operates from a single external supply on V_CC. The part generates output voltages on V_CC2 and V_L2 which may be adjusted by external programming resistors. It communicates all necessary signaling across the isolation barrier through LTC’s isolator μModule technology.
