Overview

The ISO7710DR is a high-performance, single-channel digital isolator providing up to 3000Vrms isolation. It utilizes Texas Instruments capacitive coupling technology to enable high-speed data transmission up to 100Mbps while maintaining low power consumption and high electromagnetic immunity.

Why Choose This Part

This device offers a high CMTI of 85kV/us and a low typical propagation delay of 11ns at 5V, ensuring timing accuracy in high-speed circuits. It supports a wide supply range from 2.25V to 5.5V, allowing it to function as a level shifter between different logic families while consuming only 1.7mA typical at 1Mbps.

Applications

Industrial Fieldbus Isolation
Provides signal isolation for UART, CAN, or RS-485 interfaces in harsh industrial environments to prevent ground loop currents.
Power Supply Feedback
Used in the feedback loop of switched-mode power supplies to provide safety isolation between primary and secondary sides.
Motor Control Logic
Isolates low-voltage microcontroller PWM signals from high-voltage gate drivers and power stages.
Battery Management Systems
Safely bridges communication across high-voltage battery stacks in energy storage systems.

Getting Started

When designing with the ISO7710DR, place 0.1uF bypass capacitors as close as possible to the VCC1 and VCC2 pins. Ensure that the PCB layout maintains the required creepage and clearance distances beneath the 8-SOIC package to meet safety certification standards. For evaluation, the ISO7710EVM can be used to test signal integrity and isolation performance.
