Product details

High-side current monitor for industrial and automotive rails

The Texas Instruments INA202AID is a high-side current monitor that senses current by measuring the voltage drop across a shunt resistor placed between the supply rail and the load. Its input common-mode range of -16V to 80V covers 12V, 24V, and 48V systems, including reverse-battery conditions and transient overvoltage events common in industrial motor drives and automotive body controllers. The ±3.5% accuracy is adequate for overcurrent protection thresholds and load monitoring, though not for precision metering applications.

It is ROHS3 compliant.

Frequently asked questions

What is INA202AID's listed accuracy?

The accuracy is ±3.5%. This is the total measurement error across the full input range and temperature span — sufficient for fault detection and load monitoring, not for precision current measurement.
