INA193AIDBVR Current Monitor Regulator High-Side SOT-23-5
The INA193AIDBVR is a Texas Instruments high-side current shunt monitor packaged in compact SOT-23-5, featuring fixed 20V/V voltage gain and supporting a wide common-mode input voltage range from -16V to +80V, independent of its supply rail. It operates from a single 2.7V to 18V power supply with 500kHz bandwidth and 1V/μs slew rate, delivering analog voltage output proportional to the current across an external shunt resistor. This current sensing IC works over the industrial temperature range of -40°C to 125°C with maximum 3% total error across full temperature, ideal for high-side current measurement in power management and battery monitoring systems.
Key Features
● Wide common-mode voltage of -16V to +80V, enabling high-side current detection on high voltage power rails.
● Fixed 20V/V gain, 500kHz bandwidth and fast 1V/μs slew rate suitable for dynamic current loop control.
● Single supply operation from 2.7V to 18V with maximum 900µA quiescent current for low power consumption.
● Maximum 3% total error over full temperature range, providing reliable current reading for industrial applications.
● Strong common-mode rejection ratio and low input offset voltage to minimize measurement noise and drift.
FAQ: Can INA193AIDBVR measure bidirectional current? It measures unidirectional current only. Use a low tolerance shunt resistor and place the sensing traces close to the IC input pins to reduce noise and improve measurement precision.
