ZXCT215QCDW-7

Overview

The ZXCT215QCDW-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 a SOT-363-6 surface-mount package. This specific variant offers a gain of 75V/V and belongs to the 'C' type series, which provides 0.5% gain linearity. It supports both high-side and low-side current sensing applications across a temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift topology ensures high precision with minimal offset drift
• Wide common-mode sense range from -0.3V to 26V independent of supply voltage
• Supports bidirectional current measurement via reference pin
• Available in automotive-grade Q-series variants for enhanced reliability

Applications

• High-side and low-side current monitoring in power systems
• Battery management systems requiring precise current tracking
• Industrial equipment protection circuits
• Automotive electronics current sensing applications

Procurement Notes

Verify the specific suffix 'QCDW' matches the required gain (75V/V), package (SOT-363), and automotive qualification status. Confirm RoHS compliance details and check for alternative tape-and-reel quantities if standard packaging does not align with production needs. Ensure the ordering part number corresponds exactly to the datasheet specifications for the C-type variant.

Selection Notes

Select this component when a 75V/V gain is required for current sensing applications. The C-type designation indicates superior gain linearity compared to A or B variants. Consider the SOT-363 package size for space-constrained designs. Verify that the 2.7V minimum operating voltage suits the system's power rails and that the wide common-mode range accommodates the shunt voltage levels.

Part Context

This part belongs to the ZXCT21xQ family of precision current shunt monitors. The family includes multiple gain options ranging from 50V/V to 1kV/V. The 'Q' suffix denotes automotive qualification, while 'C' specifies the highest precision tier with 0.5% gain linearity. These devices are designed for applications demanding high accuracy and stability over temperature variations.

Replacement Considerations

Compatible substitutes within the same family include ZXCT213QCDW-7 (50V/V gain) and ZXCT214QCDW-7 (100V/V gain). Other variants such as ZXCT210QCDW-7 (200V/V) or ZXCT211QCDW-7 (500V/V) may be used if gain adjustments are acceptable. Ensure the replacement maintains the SOT-363 package and Q-series automotive grade if required.
