NCV21674DMG200R2G

Current Regulation/Management Overview

The NCV21674DMG200R2G is a dual-channel, unidirectional current-shunt monitor from onsemi. It features a fixed voltage gain of 200 V/V and supports a common-mode voltage range from -100 mV to 40 V. The device operates within a supply voltage range of 2.7 V to 5.5 V, with a maximum operating temperature of +125 °C. Key electrical specifications include a gain error of 0.5%, an input bias current of 35 µA, and an input offset voltage of 19 µV. It provides a common-mode rejection ratio (CMRR) of 134 dB and a gain-bandwidth product of 100 kHz.

Current Regulation/Management Feature Summary

• Dual-channel architecture for simultaneous high-side or low-side current monitoring
• High precision with low input offset voltage and minimal gain error
• Wide common-mode voltage range supporting up to 40 V
• Unidirectional output configuration

Current Regulation/Management Applications

• Industrial process control systems
• Power supply current monitoring
• Battery management systems
• Motor control circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix '200R2G' confirms the 200 V/V gain and tape-and-reel packaging format. Ensure the NCV prefix requirement for automotive-grade qualification aligns with your design specifications. Confirm the 8-MSOP package dimensions match your PCB footprint constraints before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when dual-channel monitoring is required with a fixed 200 V/V gain. It is suitable for applications needing a 40 V common-mode range and operation up to 125 °C. Compare against the NCS21674 series if commercial-grade temperature ranges are sufficient, noting that the NCV variant offers extended thermal performance.

Current Regulation/Management Part Context

This part belongs to the NCS/NCV2167x family of current sense amplifiers. It shares architectural similarities with single-channel variants like the NCV21671 but provides two independent channels in one package. The NCV prefix indicates automotive-grade reliability standards compared to the commercial NCS series.

Current Regulation/Management Replacement Considerations

Direct substitutes include other NCV21674 variants with different gains (e.g., NCV21674DMG050R2G for 50 V/V). Single-channel equivalents like NCV21671 may require circuit redesign. Verify pin compatibility and gain accuracy requirements when cross-referencing.
