Key Features
- Integrated precision shunt resistor eliminates external component selection and resistor matching errors in current measurement designs
- Bidirectional zero-drift architecture enables accurate current measurement in both directions across a 36 V common-mode voltage range
- Low- or high-side placement flexibility allows current sensing at either the supply rail or ground rail without redesigning the measurement circuit
Applications
The INA250 is used in battery management systems, motor control drives, and power supply monitoring circuits where accurate bidirectional current measurement from a single integrated device simplifies design and reduces calibration effort. Its zero-drift amplifier architecture maintains measurement accuracy over temperature without offset drift errors that degrade precision in slow-moving or DC current applications. The 36 V common-mode range accommodates both low-voltage lithium battery stacks and higher-voltage industrial power rails within a single current monitor IC.

Frequently Asked Questions
What common-mode voltage range does the INA250 support for current shunt monitoring?
The INA250 supports a common-mode voltage range up to 36 V, enabling both low-side and high-side current measurement in battery management systems, 24 V industrial supplies, and motor drive circuits without exceeding the device's input rating.
How does the integrated shunt resistor in the INA250 simplify current sensing circuit design?
The INA250 integrates a precision shunt resistor directly into the package, eliminating the need for an external current sense resistor with tight tolerance and low temperature coefficient, which reduces BOM by 1 component and removes the resistor value selection step from the design process.
What does zero-drift architecture mean for the INA250's measurement accuracy over temperature?
Zero-drift architecture uses auto-zeroing or chopper stabilization techniques to suppress amplifier offset voltage drift, keeping the INA250's current measurement error below a few microvolts across the full temperature range, which is critical in battery state-of-charge algorithms and precision power metering.
Can the INA250 measure current flowing in both directions, and what applications benefit from this?
Yes, the INA250 measures bidirectional current, detecting both charging and discharging current in battery pack management systems, as well as regenerative braking current in motor drives, where current reversal occurs frequently and must be accurately quantified for energy accounting.
