INA198AIDBVT

Current Regulation/Management Overview

The INA198AIDBVT is a high-side current shunt monitor manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 18 V and draws a typical supply current of 900 uA. The device provides accurate current sensing with a specified accuracy of 3%. It is designed for operation across a wide temperature range, functioning reliably from -40 C to +125 C. The component is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained applications requiring precise power monitoring.

Current Regulation/Management Feature Summary

• Supports high-side current measurement capabilities
• Operates on single supply voltages between 2.7 V and 18 V
• Provides accurate current monitoring with defined error margins

Current Regulation/Management Applications

• Current and power monitoring systems
• Battery management circuits
• Overcurrent protection designs

Current Regulation/Management Procurement Notes

Verify the specific suffix DBVT confirms the SOT-23-5 package and tape-and-reel or cut-tape availability through authorized channels. Confirm RoHS compliance status via official documentation before integration. Ensure the ordering part number matches the required accuracy grade and temperature rating for your specific design constraints.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required within an 18 V limit. Consider the 900 uA quiescent current for battery life calculations. Verify that the SOT-23-5 footprint fits the PCB layout. Compare against other INA19x variants if different gain or package options are needed.

Current Regulation/Management Part Context

This device belongs to the INA198 series of current monitors from Texas Instruments. It is categorized under Current & Power Monitors & Regulators within the PMIC family. The component serves as a solution for detecting current flow across shunt resistors in low-voltage systems.

Current Regulation/Management Replacement Considerations

Check for direct pin-compatible substitutes within the INA19x family. Verify functional equivalence regarding input voltage range and accuracy specifications before substitution.
