ZXCT215QADW-7

Overview

The ZXCT215QADW-7 is a precision current shunt monitor from the ZXCT21xQ family, manufactured by Diodes Incorporated. It features a common-mode voltage output and operates within an input voltage range of 2.7 V to 26 V. The device utilizes a zero-drift topology for high accuracy and is available in an SOT-363-6 package. This specific variant offers a gain of 75 V/V and belongs to the automotive-grade Q-series, supporting operation temperatures from -40°C to +125°C.

Feature Summary

• Zero-drift topology ensures high precision with low offset voltage
• Supports both high-side and low-side current sensing
• Automotive-grade qualification for reliability
• Wide common-mode sense range independent of supply voltage

Applications

• Automotive battery monitoring systems
• Industrial power distribution units
• High-side current sensing in motor control
• Battery management system (BMS) protection circuits

Procurement Notes

Verify the AEC-Q100 qualification status directly with the manufacturer or authorized distributors, as this indicates automotive grade compliance. Confirm the specific suffix 'Q' denotes the qualified version distinct from standard industrial parts. Ensure the SOT-363-6 package matches your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a 75 V/V gain is required for precise current measurement in automotive environments. Compare against other ZXCT21xQ variants if different gain factors like 50 V/V or 100 V/V are needed. Ensure the 26 V maximum common-mode voltage aligns with your system's rail specifications.

Part Context

This part belongs to the ZXCT21xQ series of precision current monitors designed for automotive applications. The series includes multiple gain options ranging from 50 V/V to 1 kV/V. All members share the zero-drift architecture and wide common-mode range, differing primarily in gain and specific offset characteristics defined by their suffix letters.

Replacement Considerations

ZXCT215ADW-7 serves as the non-qualified industrial equivalent with identical electrical performance but lacks automotive certification.
