TIISOW7841DWER
Overview
The ISOW7841DWER is a high-performance, quad-channel digital isolator with an integrated high-efficiency power converter that eliminates the need for a separate isolated power supply. It provides 5000Vrms isolation and supports data rates up to 100Mbps while maintaining high common-mode transient immunity of 100kV/us. This device is designed to simplify the design of isolated interfaces like SPI and UART in space-constrained industrial applications.
Why Choose This Part
By integrating the DC-DC converter into the 16-SOIC package, it significantly reduces PCB area and BOM complexity compared to discrete transformer solutions. It operates across a wide 3V to 5.5V supply range and maintains robust performance in harsh environments with a wide operating temperature range of -40C to 125C.
Applications
Key Specifications
Getting Started
When designing the PCB layout, place 0.1uF and 10uF bypass capacitors as close as possible to the VDD and VISO pins to minimize EMI and ensure power stability. Engineers can evaluate performance using the ISOW7841EVM evaluation module, which provides a reference layout for the integrated transformer and isolation barrier. Ensure the 7.5mm wide SOIC footprint includes the required creepage and clearance distances for your specific safety standard.
