ISO7762DBQ

Overview

The ISO7762DBQ is a reinforced six-channel digital isolator from Texas Instruments, featuring a 4/2 channel configuration. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3000 Vrms. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, rise/fall times of 3.9 ns, and pulse width distortion of 0.4 ns. It is housed in a 16-SSOP package and functions across an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced isolation for six independent channels using capacitive coupling technology.
• Ensures robust electromagnetic compatibility (EMC) performance for reliable signal transmission.
• Supports high-speed data communication with a maximum rate of 100 Mb/s.
• Offers bidirectional or unidirectional signal path configurations.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high-voltage separation needs
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix 'DBQ' corresponds to the tube packaging format, as other suffixes like 'DBQR' indicate tape-and-reel options. Confirm that the component meets the required reinforced isolation standards for your specific application safety regulations. Check for current manufacturing status, as some listings may indicate end-of-life or obsolete status for this specific package variant.

Selection Notes

Select this component when reinforced isolation certification is mandatory rather than basic isolation. Ensure the system design accommodates the 16-pin SSOP footprint and the specified thermal dissipation requirements. Verify that the 3000 Vrms insulation rating aligns with the peak working voltage of the isolated circuit segments.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators. It serves as a general-purpose solution for replacing optocouplers in space-constrained designs. The device integrates six independent channels into a single compact package, reducing board area compared to discrete isolation solutions.

Replacement Considerations

Check for alternative package types such as SOIC or WSON if SSOP availability is limited. Consider the automotive-grade ISO7762QDBQQ1 if AEC-Q100 qualification is required for the application.
