Isolators with transformer driver for EV, industrial, test and medical applications

29-03-2019 | Analog Devices | Power

Analog Devices/Linear Technology LTM2810 µModule Isolators with Transformer Driver are complete galvanic digital isolators with SPI, I2C, and master mode only compatible variants. These isolators do not need external components. The µModule isolators are powered on each side by 3V to 5.5V supplies. Separate logic supply pins enable simple interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply. The isolators combine an integrated transformer driver on the logic side and an LDO on the isolated side to regulate the rectified transformer output.

The isolators offer coupled inductors that give 7500VRMS of isolation between the input and output logic interface. These isolators are excellent for systems with different ground potentials and enable uninterrupted communication through large common mode transients faster than 50kV/µs.

Typical applications include EV/HEV systems, industrial and metering systems, test and measurement equipment, and medical equipment.
