TI ISOW7721 Two-Channel Digital Isolator
Texas Instruments ISOW7721 Dual-Channel Digital Isolator is a galvanically isolated digital isolator with an integrated low-radiation, high-efficiency power converter. The integrated converter provides up to 550mW of isolated power. This feature eliminates the need for a separate isolated power supply in space-constrained isolated designs. If additional power is required, the Texas Instruments ISOW7721 supports multi-device linking, using two devices in the system to increase the integrated power output to
