Overview
The ISOW7840DWER from Texas Instruments is a quad-channel, reinforced digital isolator with an integrated high-efficiency power converter. This device is part of the ISOW784x family, designed to provide robust isolation and high electromagnetic immunity. It is packaged in a 16-pin SOIC wide-body (SOIC-WB) DWE package, making it suitable for space-constrained isolated designs. The integrated DC-DC converter eliminates the need for a separate isolated power supply, offering up to 650 mW of isolated power with various input and output voltage configurations.
