ISO6521QDRQ1

Overview

The ISO6521QDRQ1 is a dual-channel automotive digital isolator from the ISO652x-Q1 series, manufactured by Texas Instruments. It provides galvanic isolation with a rated insulation voltage of 450 Vrms and supports data rates up to 50 Mb/s. The device operates within a supply voltage range of 1.71 V to 5.5 V and features a propagation delay of 11 ns. It is housed in an SOIC-8 package and functions unidirectionally. The component is qualified for AEC-Q100 standards and operates reliably across a temperature range of -40°C to +125°C.

Feature Summary

Provides functional galvanic isolation suitable for automotive applications
Supports high-speed data transmission at rates up to 50 Mb/s
Includes a shutdown feature for power management control

Applications

Automotive electronic control units (ECUs)
Inverter gate drive circuits
Isolated communication interfaces such as UART and GPIO

Procurement Notes

Verify the specific suffix QDRQ1 confirms the automotive qualification and SOIC-8 packaging. Ensure compatibility with system voltage levels between 1.71 V and 5.5 V. Confirm that the unidirectional signal flow aligns with the circuit design requirements. Check for moisture sensitivity handling instructions during assembly.

Selection Notes

Select this component when automotive reliability and functional safety are required. It is appropriate for designs needing dual-channel isolation with moderate data speeds. Consider the SOIC-8 footprint for PCB layout constraints. Evaluate the 450 Vrms insulation rating against the system's isolation voltage requirements.

Part Context

This part belongs to the ISO652x-Q1 family of general-purpose dual-channel automotive functional isolators. It shares architectural similarities with other members like the ISO6521DR but differs in automotive qualification status. The series is designed to replace optocouplers in modern automotive systems.
