INA209AIPWG4

Current Regulation/Management Overview

The INA209AIPWG4 is a high-side bidirectional current and power monitor manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and features an accuracy of 1%. The device draws a typical operating supply current of 1.5 mA. It supports common-mode input voltages from 0 V to 26 V. The component is housed in a 16-TSSOP package with a maximum width of 4.40 mm. It is rated for operation across a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Bidirectional current measurement capability for monitoring flow in both directions.
• Integrated power monitoring functionality alongside current sensing.
• High-side sensing architecture allowing placement between the power source and load.

Current Regulation/Management Applications

• Battery management systems requiring precise charge/discharge monitoring
• Industrial process control equipment needing high-side current feedback
• Power distribution units for monitoring load currents

Current Regulation/Management Procurement Notes

Verify that the ordering suffix 'G4' corresponds to the specific RoHS-compliant version required for your assembly, as this indicates lead-free status. Confirm the package type matches your PCB footprint requirements. Ensure the supply voltage constraints align with your system design before procurement.

Current Regulation/Management Selection Notes

Select this component when bidirectional current monitoring is necessary within a low-voltage system. The 1% accuracy suits applications requiring moderate precision. Consider the 16-pin TSSOP package for space-constrained designs. Verify that the 26 V common-mode limit meets your circuit's voltage levels.

Current Regulation/Management Part Context

This part belongs to the INA209 series of current monitors. It is functionally similar to the INA209AIPWR but includes the G4 suffix indicating compliance with specific environmental standards. It serves as a solution for monitoring power consumption in battery-operated or industrial devices.

Current Regulation/Management Replacement Considerations

The INA209AIPWR is a direct functional equivalent without the G4 suffix. Check datasheets for any minor differences in packaging or environmental certifications before substitution.
