INA181A2IDBVR – TI 26V Bidirectional Current-Sense Amplifier

INA181A2IDBVR is a Texas Instruments voltage-output, bidirectional current-sense amplifier designed for accurate low-side and high-side current measurement. With a -0.2V to +26V common-mode range, 50V/V fixed gain, bidirectional sensing capability and compact 6-pin SOT-23 package, it is suitable for power monitoring, motor control, battery systems, DC/DC converters, lighting control and overcurrent detection circuits.

PackageDBV / SOT-23-6

Engineering note: Always verify the latest TI datasheet, shunt resistor value, REF pin bias, input common-mode voltage, output range and PCB layout before final production approval.

Component Overview

INA181A2IDBVR belongs to the TI INA181 family of bidirectional low- and high-side current-sense amplifiers. It measures the small differential voltage across a current-sense resistor and outputs an amplified voltage that can be read by an ADC, MCU, comparator or control loop.

TomatoElec view: INA181A2IDBVR is useful when a design needs bidirectional current monitoring with a fixed 50V/V gain. Its value comes from wide common-mode sensing, bidirectional current detection, low power consumption and compact SOT-23-6 packaging.

Circuit Function & Design Role

Bidirectional Current Monitoring

Measures current flow in both directions when the REF pin is biased properly, making it useful for charge and discharge current sensing.

High-Side Sensing

Allows current measurement on the supply side while the load remains referenced to system ground.

Low-Side Sensing

Can also be used near ground for current feedback, protection and load-current measurement.

50V/V Gain Scaling

The A2 gain option provides higher output scaling than A1, helping improve signal level when the shunt voltage is small.

Design reminder: Current-sense accuracy depends on shunt resistor tolerance, layout symmetry, input filtering, REF pin stability, common-mode voltage and ADC reference accuracy. Kelvin connection to the shunt resistor is recommended for better measurement reliability.

Application Scenarios

Battery Current Monitoring

Suitable for charge and discharge current measurement in battery packs, portable equipment and energy storage systems.

Motor Control

Used for supply-current or phase-current feedback in motor-drive systems and current control loops.

Power Management

Helps monitor load current, supply current and system power consumption in embedded and industrial equipment.

DC/DC Converters

Provides current feedback for converter protection, load monitoring and power-stage control.

TomatoElec Quality & Supply Notes

As an in-stock independent distributor and electronic components supplier, TomatoElec supports INA181A2IDBVR sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For current-sense amplifiers, correct gain option, package type and original sourcing are important because the device affects current measurement accuracy and protection behavior.

Original component sourcing: support sourcing of original Texas Instruments amplifier ICs for customer BOM requirements.
Inventory support: help customers confirm available stock, package condition, date code and shipment schedule.
Gain option verification: confirm the A2 50V/V gain option before shipment, especially when comparing with INA181A1, INA181A3 or INA181A4 versions.
BOM matching: verify gain, bidirectional sensing, common-mode range, supply voltage, package and temperature requirements before approving any substitute.

Replacement & BOM Matching Guidance

INA181A2IDBVR should not be replaced only by matching the current-sense amplifier category. Engineers should also compare gain, bidirectional sensing method, REF pin usage, common-mode voltage range, offset voltage, bandwidth, supply voltage, output swing, package, pinout and temperature range.

Selection tip: For customer BOM replacement, confirm whether the design requires the A2 50V/V gain version. A different gain option may change ADC scaling, current-limit thresholds, bidirectional zero-current reference and firmware calibration.

FAQ

What is INA181A2IDBVR used for?

INA181A2IDBVR is used for bidirectional current measurement, power monitoring, motor control feedback, battery charge/discharge sensing, DC/DC converter protection and overcurrent detection.

What does A2 mean in INA181A2IDBVR?

The A2 option indicates a fixed gain of 50V/V. This gain must match the shunt resistor value, ADC input range and current measurement requirement of the target design.

How is INA181A2IDBVR different from INA180A2IDBVR?

INA181A2IDBVR supports bidirectional current sensing through the REF pin, while INA180 devices are typically used for unidirectional current-sensing applications. Designers should confirm the sensing direction and reference requirements before substitution.

Can TomatoElec support INA181A2IDBVR sourcing?

TomatoElec can support INA181A2IDBVR inquiry, inventory confirmation, BOM sourcing and shipment coordination. Customers are recommended to confirm required quantity, gain option, package condition, date code preference and delivery schedule before ordering.

Final Selection Summary

INA181A2IDBVR is a compact bidirectional current-sense amplifier for designs that require accurate current measurement, 50V/V gain and a small SOT-23-6 package. Its main value is in battery systems, power monitoring, motor control, DC/DC converters and protection circuits.

TomatoElec recommendation: Use INA181A2IDBVR when the BOM requires Texas Instruments bidirectional current-sense amplifier technology, A2 50V/V gain, low/high-side sensing capability and DBV / SOT-23-6 packaging. Before production or replacement, verify shunt resistor value, REF pin bias, input common-mode range, output swing, PCB layout and measurement accuracy target.
