ZXCT213BDSJ-7

Overview

The ZXCT213BDSJ-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, offering a gain of 50 V/V with a 'C' variant providing 0.5% gain linearity. It supports both high-side and low-side measurements via a reference pin for bidirectional current sensing. The component is housed in a U-QFN1418-10 package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift topology ensures high precision and stability
• Supports bidirectional current measurement through a dedicated reference pin
• Enables flexible high-side and low-side sensing configurations

Applications

• Precision current monitoring in power management systems
• Battery management system (BMS) current sensing
• Industrial equipment power regulation

Procurement Notes

Verify the specific suffix 'DSJ' against official Diodes Incorporated documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint requirements for the U-QFN1418-10 package. Cross-reference the datasheet for any recent design changes or environmental compliance updates before finalizing procurement.

Selection Notes

Select this component when high accuracy and low offset voltage are critical for current sensing applications. The 50 V/V gain is suitable for detecting small voltage drops across shunt resistors. Consider the 'C' variant characteristics if stringent linearity and minimal drift are required over the operating temperature range.

Part Context

This part belongs to the ZXCT21xQ series of precision current monitors. The family includes various gain options such as 75 V/V, 100 V/V, and higher values. These devices share a common architecture designed for automotive and industrial applications requiring robust performance under varying thermal conditions.

Replacement Considerations

Check for other members of the ZXCT21xQ family with different gains if signal scaling needs adjustment. Verify pinout compatibility with existing designs when considering alternative packages like SOT-363.
