ISOW7841FAQDWERQ1

Overview

The ISOW7841FAQDWERQ1 is an automotive-grade, reinforced quad-channel digital isolator featuring an integrated high-efficiency DC-DC converter. It provides a 5000-Vrms isolation rating with 100 kV/µs common-mode transient immunity. The device supports data rates up to 100 Mbps and operates within a temperature range of -40°C to +125°C. It utilizes a 16-pin SOIC package and accepts supply voltages between 3 V and 5.5 V.

Feature Summary

• Integrates a high-efficiency, low-emissions DC-DC converter for isolated power generation
• Provides reinforced insulation with 5000-Vrms capability for safety-critical applications
• Delivers high-speed data transmission at 100 Mbps with low propagation delay
• Features 100 kV/µs common-mode transient immunity for robust noise rejection

Applications

• Automotive inverter control systems
• On-board charging (OBC) interfaces
• Battery management system (BMS) communication
• Electric vehicle motor drive isolation

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the 'FDWE' package code matches the required 16-SOIC footprint and thermal characteristics. Confirm the datasheet revision aligns with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when reinforced isolation and integrated power conversion are required in a single package. It is suitable for designs needing high CMTI and bidirectional or unidirectional signal isolation in automotive environments. Compare channel configurations against other ISOW7841 variants if different input/output ratios are needed.

Part Context

This part belongs to the ISOW7841A family of Texas Instruments digital isolators. It combines capacitive coupling technology with magnetic coupling for the internal DC-DC converter. The series is designed to replace bulky discrete solutions by integrating isolation barriers and power management into a compact surface-mount package.

Replacement Considerations

Check ISOW7841AQDWERQ1 for identical electrical specifications but potentially different packaging quantities. Verify ISOW7841A-Q1 variants for equivalent performance metrics while confirming package compatibility.
