INA201AID

Current Regulation/Management Overview

The INA201AID is a high-side current shunt monitor manufactured by Texas Instruments. It operates with a supply voltage range of 2.7 V to 18 V and features an accuracy of 3.5%. The device draws a typical operating supply current of 1.85 mA. It is housed in an 8-pin VSSOP package and supports surface mount installation. The component functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Provides high-side current measurement capabilities for monitoring applications
• Features low power consumption suitable for battery-operated systems
• Offers wide common-mode voltage range compatibility

Current Regulation/Management Applications

• Current and power monitoring in industrial systems
• Overcurrent protection circuitry
• Battery management systems

Current Regulation/Management Procurement Notes

Verify the specific suffix against official documentation, as variations exist between tape-and-reel and tube packaging formats. Confirm that the requested variant matches the required pinout and thermal characteristics for your design. Cross-reference the manufacturer's latest datasheet to ensure the part remains active and compliant with current environmental standards before finalizing procurement plans.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required within an 18 V common-mode limit. The 3.5% accuracy meets general monitoring needs but may require calibration for precision applications. Ensure the PCB layout accommodates the VSSOP-8 footprint and consider thermal dissipation requirements given the operating temperature range up to 125°C.

Current Regulation/Management Part Context

The INA201 belongs to Texas Instruments' family of current shunt monitors designed for simple, cost-effective current sensing solutions. Unlike integrated power monitors, this device provides only the amplified voltage output proportional to the shunt resistor drop, requiring external calculation or ADC integration for power readings.
