Design a Custom BoardAbout This Component
High-precision current shunt monitor that measures DC current through a low-value sense resistor. Features 0.5% accuracy and operates with supply voltages from 2.7V to 5.5V. Outputs a proportional voltage (typically 1.3V per amp) for direct ADC conversion. Ideal for battery management systems, power distribution circuits, and load monitoring applications.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
