Design a Custom BoardAbout This Component
Precision supply voltage supervisor for 3V, 3.3V, and 5V systems with active-low push-pull reset output and manual reset input. Monitors VCC and generates 140ms minimum reset pulse, operating from 1.0V to system voltage with typical supply current of 6µA. Designed for microcontroller and digital circuit power management in industrial temperature range (-40 to 85°C).
Package: SOT-143 · 4 pins
Why does this need a breakout?
SOT-143 is a tiny surface-mount package with 0.65mm pin pitch, making hand soldering impractical and breadboard use impossible. A breakout board converts these compact supervisory circuits, MOSFETs, and transistor arrays to through-hole pins, enabling rapid prototyping without reflow equipment or fine soldering skills.
