INA216A1RSWT

Current Regulation/Management Overview

The INA216A1RSWT is a unidirectional current shunt monitor from Texas Instruments' Zero-Drift series. It operates within a supply voltage range of 1.8 V to 5.5 V and draws a typical quiescent current of 30 µA. The device features a fixed gain of 50 V/V and supports input common-mode voltages up to 26 V. It is housed in a UQFN-10 package with an operating temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Zero-drift architecture minimizes offset voltage drift over temperature for high accuracy
• Unidirectional measurement capability simplifies integration in single-direction current sensing applications
• Ultra-low power consumption enables extended battery life in portable systems

Current Regulation/Management Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Current Regulation/Management Procurement Notes

Verify the specific suffix 'WT' indicates tape-and-reel packaging when ordering. Confirm the 'A1' variant corresponds to the required gain and accuracy specifications for your design. Ensure the UQFN-10 footprint matches your PCB layout constraints. Check RoHS compliance status if required by your manufacturing standards.

Current Regulation/Management Selection Notes

Select this component for applications requiring low quiescent current and high precision without external calibration. The fixed 50 V/V gain suits shunts producing small voltage drops. Consider the 26 V common-mode limit for high-side sensing. The unidirectional nature restricts use to positive current flow only.

Current Regulation/Management Part Context

This part belongs to the INA216 family of small-size, low-power current monitors. It shares the Zero-Drift technology with other variants like the INA216A2 and INA216A3, differing primarily in gain settings and initial accuracy grades. The RSWR/RSWT suffixes denote the UQFN-10 package type.

Current Regulation/Management Replacement Considerations

INA216A2RSWT and INA216A3RSWT are pin-compatible alternatives within the same series offering different gain factors. For bidirectional sensing, consider the INA219 or INA226 families instead.
