IC SUPERVISOR 1CH RESET SOT23-3


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardMicroprocessor supervisor IC that monitors VCC supply voltage and generates active-low reset signals when supply falls below the threshold. Supports precision monitoring at 1.5V to 5.0V with selectable reset pulse widths (1ms to 140ms) and requires no external components. Ultra-low 0.5µA quiescent current makes it ideal for battery-powered and embedded systems requiring robust power-supply monitoring.
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.
