DC1263A: Demo Board for the LTC4558 Dual SIM/Smart Card Power Supply and Interface

DC1748A-C: Demo Board for LTM2883 SPI/Digital or I2C μModule Isolator with Adjustable ±12.5V and 5V Regulated Power.

The LTM2887 is a complete galvanic digital ?Module? (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 2500VRMS 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/?s.Applications Isolated SPI or I2C Interfaces Industrial Systems Test and Measurement Equipment Breaking Ground Loops

The LTM2885 is a complete galvanically isolated full-duplex RS485/RS422 ?Module? (micromodule) transceiver. No external components are required. A single supply powers both sides of the interface through an integrated, isolated, low noise, efficient 5V output DC/DC converter.Coupled inductors and an isolation power transformer provide 6500VRMS of isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop is broken allowing for large common mode voltage variation. Uninterrupted communication is guaranteed for common mode transients up to 50kV/?s.Maximum data rates are 20Mbps or 250kbps in slew limited mode. Transmit data, DI, and receive data, RO, are implemented with event driven low jitter processing. The receiver has a one-eighth unit load supporting up to 256 nodes per bus. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Enhanced ESD protection allows this part to withstand up to ?15kV (human body model) on the transceiver interface pins to isolated supplies and ?25kV through the isolation barrier to logic supplies without latch-up or damage.APPLICATIONS Isolated RS485/RS422 Interface Industrial Networks Breaking RS485 Ground Loops Isolated PROFIBUS-DP Networks
