INA194AIDBVT

Current Regulation/Management Overview

The INA194AIDBVT is a high-side current sense amplifier manufactured by Texas Instruments, designed for monitoring current and power in single-supply systems. It operates with a supply voltage range of 2.7 V to 18 V and supports common-mode input voltages from -0.1 V to 26 V. The device features a fixed gain of 20 V/V, ensuring accurate amplification of shunt voltage drops. It includes an internal reference voltage and offers a bandwidth of 500 kHz with a low quiescent current of 900 µA. Packaged in a five-pin SOT-23 format, it functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Procurement Notes

Verify the specific suffix 'VT' indicates the tape-and-reel packaging variant when ordering. Confirm that the component meets RoHS compliance requirements for your region. Ensure the supplier provides valid traceability documentation. Check for moisture sensitivity level ratings prior to soldering. Validate that the part number matches the exact gain and package configuration required for your schematic.

Current Regulation/Management Selection Notes

Select this component when high-side monitoring is required within a 2.7 V to 18 V system. The fixed 20 V/V gain reduces external resistor needs compared to programmable alternatives. Consider the 500 kHz bandwidth for applications requiring fast transient response. The SOT-23-5 package suits space-constrained designs. Verify thermal dissipation capabilities if operating near maximum temperature limits.

Current Regulation/Management Part Context

This device belongs to the INA194 family of current sense amplifiers from Texas Instruments. It shares architectural similarities with other members but differs in specific gain settings and package options. The family targets general-purpose current monitoring tasks. The 'A' designation typically denotes a specific accuracy grade or temperature range extension within the series lineup.
