ISO7330CQDWQ1

Overview

The ISO7330CQDWQ1 is an automotive-grade, low-power, triple-channel digital isolator from Texas Instruments. It features unidirectional signal transmission with a data rate of 25 Mb/s and a propagation delay of 36 ns. The device provides 3000 Vrms isolation voltage via capacitive coupling and operates within a supply voltage range of 3 V to 5.5 V. It draws a typical operating current of 7 mA and supports a wide temperature range from -40°C to +125°C. Packaged in a 16-pin SOIC (DW) format, it holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Provides galvanic isolation for three independent signal channels using capacitive coupling technology.
• Designed for automotive applications with robust electromagnetic compatibility performance.
• Operates on a single power supply rail ranging from 3 V to 5.5 V.
• Ensures high common-mode transient immunity for reliable data transmission.

Applications

• Automotive gateway systems requiring isolated communication interfaces
• Inverter control circuits in electric vehicle powertrains
• Battery management system monitoring and protection
• Charging station controller isolation barriers

Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-16 package and tube packaging configuration. Ensure the 'Q1' designation matches your automotive grade requirements. Confirm that the 25 Mb/s data rate meets your system timing constraints. Check for AEC-Q100 certification compliance if required by your design specifications. Validate pinout compatibility during schematic capture.

Selection Notes

Select this component when low power consumption is critical alongside moderate data rates. It serves as a suitable alternative to higher-speed isolators where 25 Mb/s is sufficient. Consider the 3000 Vrms isolation level against your system's voltage stress requirements. Compare total power dissipation against thermal limits in enclosed automotive enclosures. Evaluate the unidirectional nature against bidirectional protocol needs.

Part Context

This part belongs to the ISO733x-Q1 family of digital isolators, which emphasizes low power consumption and robust EMC performance for automotive environments. It complements other Texas Instruments interface solutions like the ISO1042 CAN transceiver. The series offers various channel configurations to support diverse isolation needs in vehicle networks.

Replacement Considerations

The ISO7330CQDWRQ1 is a reel-packaged variant of the same functional device. Verify if tape-and-reel handling is preferred over tube packaging for assembly processes. Both parts share identical electrical characteristics and pinouts.
