Design a Custom BoardAbout This Component
Watchdog timer circuit that monitors system health and prevents failures from hardware or software errors. Features selectable timeout periods (3.4ms to 1.6s), open-drain or push-pull output, chip enable control, and ultra-low 13µA quiescent current. Suitable for telecommunications, industrial equipment, automotive, medical, and UPS applications with automotive qualification and ESD protection to 2kV.
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.
