INA195AIDBVT

Current Regulation/Management Overview

The INA195AIDBVT is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current sensing in power management applications. It operates with a supply voltage range of 2.7 V to 18 V and supports common-mode input voltages from -16 V to +80 V. The device features a fixed gain of 100 V/V and maintains an accuracy of 3%. It draws a typical operating supply current of 900 uA and functions reliably within a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount case, it integrates into systems requiring efficient power monitoring.

Current Regulation/Management Feature Summary

• Supports wide common-mode voltage range from -16 V to +80 V for flexible high-side placement
• Provides fixed 100 V/V gain for direct interface with analog-to-digital converters
• Ensures measurement accuracy within 3% across the specified industrial temperature range

Current Regulation/Management Applications

• Battery management systems in portable electronics
• Overcurrent protection circuits in industrial equipment
• Power monitoring in computing and data center infrastructure

Current Regulation/Management Procurement Notes

Verify the specific suffix DBVT confirms the tape-and-reel packaging format upon ordering. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the design accounts for the humidity sensitivity level indicated in the datasheet. Validate that the -16 V to +80 V common-mode range aligns with the target circuit's voltage levels. Check for any recent product change notices affecting pinout or electrical characteristics.

Current Regulation/Management Selection Notes

Select this component when a high-side configuration is required with a wide common-mode voltage span. The fixed 100 V/V gain simplifies signal conditioning compared to adjustable gain alternatives. Consider the 900 uA supply current for low-power battery-operated designs. The SOT-23-5 package offers space efficiency for dense PCB layouts. Verify thermal performance requirements against the specified junction-to-ambient characteristics.

Current Regulation/Management Part Context

This part belongs to the INA19x family of current shunt monitors from Texas Instruments. It shares architectural similarities with the INA193 and INA198 but differs in specific gain and bandwidth specifications. The family is designed for cost-effective current sensing solutions in various power management scenarios. The DBVT suffix denotes the specific reel packaging variant used for automated assembly processes.

Current Regulation/Management Replacement Considerations

The INA195AIDBVTG4 is listed as a discontinued version of this component. The INA195AIDBVT is the recommended manufacturer replacement for the G4 suffix variant. Other family members like INA193 or INA198 may serve as functional alternatives if gain or bandwidth differences are acceptable.
