Overview
The ZXCT212QCDW-7 is a precision current shunt monitor from the ZXCT21xQ family, manufactured by Diodes Incorporated. It features a 'zero-drift' topology and supports both high-side and low-side measurements with a common-mode sense range of -0.3V to 26V. The device offers a gain of 1kV/V and includes a reference pin for bi-directional current measurement. It operates within an input voltage range of 2.7V to 26V and functions across a temperature range of -40°C to +125°C. The component is housed in a SOT-363-6 package.
Feature Summary
- Utilizes zero-drift topology for high precision
- Supports high-side and low-side sensing
- Enables bi-directional current measurement via reference pin
Applications
- Precision current monitoring in power systems
- Battery management systems
- Industrial control circuits
Procurement Notes
Verify the specific suffix 'Q' indicates automotive or qualified grade requirements if applicable to your design. Confirm the 'C' variant meets your offset and linearity specifications. Ensure the SOT-363-6 package fits your PCB layout constraints. Check for RoHS compliance status in the official datasheet before finalizing procurement.
Selection Notes
Select this part when a 1kV/V gain is required for low-voltage shunt applications. The ZXCT21xQ family provides multiple gain options; choose based on expected shunt voltage drop. The 'C' variant offers superior linearity compared to A or B variants. Consider the 26V common-mode range for compatibility with various supply voltages.
Part Context
This component belongs to the ZXCT21xQ series of current monitors. The family includes variants with gains ranging from 50V/V to 1kV/V. All members share the zero-drift architecture and wide common-mode input range. The ZXCT212Q specifically targets applications requiring high resolution for small differential signals.
Replacement Considerations
Other ZXCT21xQ family members (e.g., ZXCT210Q, ZXCT211Q) offer different gains but similar functionality. Verify pinout compatibility when substituting. No direct cross-brand substitutes are confirmed in public documentation.
