ISO7762DBQR

Overview

The ISO7762DBQR is a six-channel digital isolator from Texas Instruments, housed in an SSOP-16 package. It features capacitive coupling for signal isolation with a rated insulation voltage of 3000 Vrms. The device supports data rates up to 100 Mb/s and operates on a supply voltage range of 2.25 V to 5.5 V. It includes four forward channels and two reverse channels, offering bidirectional and unidirectional polarity options. Key electrical parameters include a propagation delay of 11 ns, rise and fall times of 3.9 ns, and a typical operating supply current of 25.7 mA. The component functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility performance suitable for noisy industrial environments
• Offers reinforced insulation capabilities for safety-critical applications requiring high isolation integrity
• Integrates six isolated channels in a compact surface-mount package to reduce board space

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering and energy management circuits
• Inverter drives and motor control interfaces

Procurement Notes

Verify the specific suffix DBQR indicates reel packaging when ordering. Confirm that the required insulation rating meets the application's safety standards, as this part provides 3000 Vrms reinforced isolation. Ensure the design accounts for the specified operating temperature range and supply voltage constraints. Cross-reference the datasheet for humidity sensitivity handling requirements during assembly.

Selection Notes

Select this component when six isolated channels are required in a single package. It is suitable for designs needing high common-mode transient immunity and robust EMC performance. Consider the 100 Mb/s data rate limit and 3000 Vrms insulation rating against system requirements. Compare power consumption and channel configuration against alternatives if fewer channels or different isolation voltages are sufficient.

Part Context

This part belongs to the ISO776x family of high-speed, robust EMC, reinforced six-channel digital isolators. It shares the SSOP-16 footprint with other members like the ISO7763DBQR but differs in channel directionality and insulation ratings. The family utilizes capacitive coupling technology to provide reliable signal transmission across isolation barriers.

Replacement Considerations

The ISO7763DBQR is a related six-channel isolator with three forward and three reverse channels. Verify channel directionality requirements before substitution, as the ISO7762DBQR has a fixed 4-forward/2-reverse configuration.
