Design a Custom BoardAbout This Component
Single-channel supervisory circuit in SOT23-3 package for microprocessor reset monitoring and power supply supervision. Monitors supply voltage and provides open-drain reset output when voltage falls below threshold. Typical applications include system reset generation, processor restart on brownout, and watchdog functionality in embedded systems.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
