ISOW7841DWE

Overview

The ISOW7841DWE is a high-performance, reinforced quad-channel digital isolator from Texas Instruments featuring an integrated high-efficiency DC-DC converter. It provides four independent signal channels with unidirectional data flow and supports data rates up to 100 Mbps. The device offers 5000-Vrms reinforced isolation and 100 kV/µs common-mode transient immunity. It operates on a single supply voltage between 3 V and 5.5 V, drawing 54 mA of operating supply current. The propagation delay is typically 13 ns with a pulse width distortion of 600 ps. Packaged in a 16-pin SOIC (DWE) for surface mount installation.

Feature Summary

• Integrates a high-efficiency DC-DC converter to provide isolated power generation up to 650 mW
• Provides reinforced insulation with 5000-Vrms isolation rating for safety-critical applications
• Features four independent digital channels supporting data rates up to 100 Mbps
• Delivers high common-mode transient immunity of 100 kV/µs

Applications

• Automotive systems requiring reinforced isolation
• Industrial automation and control networks
• Medical equipment with strict isolation requirements
• Power metering and energy management systems

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Ensure the component meets automotive qualification standards if required for your application. Cross-reference the datasheet revision date to confirm compatibility with your design constraints. Confirm that the integrated DC-DC converter output matches your load requirements before procurement.

Selection Notes

Select this component when reinforced isolation and integrated power conversion are required in a single package. It is suitable for designs needing multiple isolated channels without external magnetics. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate the 54 mA supply current against system power budgets. Verify that the 100 Mbps data rate meets communication speed requirements.

Part Context

The ISOW7841DWE belongs to the ISOW784x family of high-performance digital isolators. This series combines signal isolation with integrated power conversion capabilities. The DWE suffix indicates a 16-pin Small Outline Integrated Circuit package. The device utilizes capacitive coupling technology for signal transmission across the isolation barrier.

Replacement Considerations

Compatible variants include ISOW7841-Q1 for automotive applications. Check ISOW7841QDWERQ1 for equivalent automotive-grade performance in the same package. Verify pinout and electrical parameters match before substitution.
