SparkFun Soft Power Switch Mk2
The SparkFun Soft Power Switch Mk2 is a compact, digital on/off switch designed for battery-powered systems. A simple press powers the system on, while a press or a long-hold (10 seconds) turns it off. It's equipped with a 74LVC1G175 D-type flip-flop for reliable performance, even in varying temperatures. It features a 2A fuse (4A peak), supports battery charging, and allows microcontroller feedback through PUSH and OFF pins for custom power management. With very low quiescent current (<1µA @ 3.75V), it’s ideal for low-power, battery-driven applications.
