INA193AIDBVT

Current Regulation/Management Overview

The INA193AIDBVT is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current sensing in power management applications. It operates with a wide common-mode voltage range from -16 V to 80 V and supports a supply voltage between 2.7 V and 18 V. The device features a fixed gain of 20 V/V, ensuring accurate amplification of the differential voltage across the shunt resistor. Key electrical specifications include a maximum input offset voltage of 2 mV, a quiescent current of 900 µA, and a bandwidth of 500 kHz. It maintains an accuracy of ±3% over the operating temperature range of -40°C to +125°C.

• Operates on a single supply voltage ranging from 2.7 V to 18 V with low quiescent current consumption.
• Delivers ±3% accuracy across the full industrial temperature range.

Current Regulation/Management Applications

• Battery management systems
• Power distribution units
• Load switch control circuits

Current Regulation/Management Procurement Notes

Verify the package type matches the required PCB footprint, as this component uses the SOT-23-5 (SC-74A) surface-mount package. Confirm that the selected variant meets the specific thermal and humidity sensitivity requirements for the intended manufacturing process. Ensure compatibility with the system's voltage levels and current sensing range before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when high-side monitoring is required within a wide common-mode voltage window up to 80 V. The fixed 20 V/V gain is suitable for applications where the output signal needs to be directly interfaced with ADCs or microcontrollers without additional scaling. Consider the 500 kHz bandwidth for dynamic load monitoring tasks.

Current Regulation/Management Part Context

This part belongs to the INA19x family of current shunt monitors from Texas Instruments. It is specifically engineered for cost-sensitive and space-constrained designs requiring reliable high-side current measurement. The device integrates precision resistors and operational amplifiers to provide a differential-to-single-ended conversion.

Current Regulation/Management Replacement Considerations

INA193AIDBVRG4 is a verified equivalent variant within the same series, offering identical electrical characteristics but potentially differing in reel packaging configuration.
