ZXCT213QBDW-7

Overview

The ZXCT213QBDW-7 is a precision current shunt monitor from the ZXCT21xQ family, manufactured by Diodes Incorporated. It features a -0.3V to 26V common-mode sense range independent of supply voltage, enabling both high-side and low-side measurements. The device provides a voltage output with a fixed gain of 50V/V. It utilizes a zero-drift topology for enhanced accuracy. The component operates within an input voltage range of 2.7V to 26V and supports an operating temperature range from -40°C to +125°C. It is housed in a SOT-363-6 surface-mount package.

Feature Summary

• Supports bidirectional current measurement via a dedicated reference pin
• Utilizes zero-drift topology to minimize offset errors
• Enables flexible high-side or low-side sensing configurations

Applications

• Precision current monitoring in industrial systems
• Power management regulation in automotive electronics
• Battery management system current sensing

Procurement Notes

Verify the specific suffix 'B' against the official datasheet to confirm the exact input offset and gain linearity specifications associated with this variant. Ensure the ordering part number matches the required package type and tape-and-reel quantity. Confirm RoHS compliance status through the manufacturer's product compliance documentation prior to final procurement.

Selection Notes

Select this component when a 50V/V gain is required for precise current monitoring applications. The zero-drift architecture makes it suitable for designs demanding high accuracy over wide temperature ranges. Consider the SOT-363-6 package constraints for PCB layout. Evaluate the -0.3V to 26V common-mode range against the maximum voltage present in the sensing circuit.

Part Context

This part belongs to the ZXCT21xQ series of precision current monitors. The family includes variants with different gains (1kV/V, 500V/V, etc.) and accuracy grades (A, B, C). The ZXCT213Q specifically denotes the 50V/V gain option within this robust portfolio designed for automotive and industrial power management.

Replacement Considerations

Other members of the ZXCT21xQ family may serve as alternatives if gain requirements differ. Variants such as ZXCT213QA or ZXCT213QC offer different accuracy grades while maintaining the same 50V/V gain. Cross-reference package compatibility and thermal performance when substituting.
