Design a Custom BoardAbout This Component
Power-on reset circuit with integrated watchdog timer and manual reset capability in a 5-pin SOT-23 package. Monitors supply voltage and system operation, asserting reset output when voltage falls below threshold or watchdog timer expires. Suitable for microcontroller supervision and system reliability applications requiring automatic reset functionality.
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.
