INA216A2YFFR

Current Regulation/Management Overview

The INA216A2YFFR is a unidirectional current shunt monitor manufactured by Texas Instruments. It operates with a common-mode voltage range of +1.8V to +5.5V and features a gain of 25V/V. The device offers an offset voltage of ±30μV and a maximum gain error of ±0.2%. It functions within a temperature range of -40°C to +125°C and is housed in a 4-DSBGA package.

Current Regulation/Management Feature Summary

• Provides high-side current sensing capability across a wide common-mode voltage range from 1.8V to 5.5V.
• Delivers high precision with low offset voltage and minimal gain error for accurate measurements.
• Utilizes a compact chip-scale package suitable for space-constrained designs.

Current Regulation/Management Applications

• Battery management systems
• Overcurrent protection circuits
• Current limiting applications

Current Regulation/Management Procurement Notes

Verify the specific suffix YFFR corresponds to the 4-DSBGA package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected gain variant matches the system design requirements for signal scaling.

Current Regulation/Management Selection Notes

Select this component when high-side monitoring is required within a 1.8V to 5.5V common-mode window. The fixed 25V/V gain suits applications where output voltage swing aligns with standard logic levels. Consider the ±30μV offset for low-current accuracy needs in portable or battery-powered devices.

Current Regulation/Management Part Context

This part belongs to the INA216 family of small-size, low-power current shunt monitors. The A2 variant specifically denotes a 25V/V gain option. The YFFR suffix indicates the specific tape-and-reel packaging format compatible with automated surface-mount assembly processes.

Current Regulation/Management Replacement Considerations

Official substitutes include other members of the INA216 family such as INA216A1YFFR (25V/V) or INA216A3YFFR (50V/V), provided the gain difference is acceptable. Verify pinout compatibility and package dimensions before substitution.
