INA216A3RSWR

Current Regulation/Management Overview

The INA216A3RSWR is a high-precision current sense amplifier from Texas Instruments, designed for monitoring current and power in systems operating with supply voltages between 1.8 V and 5.5 V. It features a fixed gain of 100 V/V and supports bidirectional current sensing. The device operates within an extended temperature range of -40°C to +125°C and consumes a typical quiescent current of 30 µA. Packaged in a compact 10-pin UQFN (RSW) format, it is optimized for space-constrained applications requiring accurate high-side or low-side current measurement.

Current Regulation/Management Feature Summary

• Provides high-precision bidirectional current sensing with a fixed internal gain of 100 V/V
• Operates on a wide single-supply voltage range from 1.8 V to 5.5 V
• Features ultra-low quiescent current consumption for energy-efficient designs
• Supports operation across an extended industrial temperature range up to 125°C

Current Regulation/Management Applications

• Battery management systems in portable electronics
• Overcurrent protection circuits in industrial equipment
• Current monitoring in consumer devices and IoT nodes
• Power regulation feedback loops in embedded systems

Current Regulation/Management Procurement Notes

Verify the specific suffix RS indicates the UQFN-10 package configuration when sourcing. Confirm the A3 grade corresponds to the required gain accuracy and offset specifications for your design. Ensure compatibility with the 1.8 V to 5.5 V supply range. Check RoHS compliance status as per manufacturer documentation. Validate that the bidirectional output capability meets your signal conditioning requirements.

Current Regulation/Management Selection Notes

Select this component when a fixed 100 V/V gain is sufficient for the expected shunt voltage drop. Consider the UQFN-10 package for board space optimization compared to larger packages. Evaluate the 30 µA quiescent current against battery life requirements. Ensure the input common-mode voltage range aligns with the system's high-side or low-side topology constraints.

Current Regulation/Management Part Context

This part belongs to the INA216 family of precision current sense amplifiers. It shares architectural similarities with other members like the INA216A2RSWR but differs in gain calibration and accuracy grades. The series is designed for general-purpose current monitoring where low power consumption and high precision are prioritized over programmable gain options found in other TI amplifier lines.

Current Regulation/Management Replacement Considerations

The INA216A2RSWR is a related variant within the same family, potentially offering different gain accuracy or offset characteristics. Verify pinout compatibility and electrical parameter alignment before substitution. No direct cross-manufacturer equivalents are confirmed in public documentation.
