SparkFun Soft Power Switch - USB-C

The SparkFun Soft Power Switch is a versatile and efficient on/off switch designed for seamless integration with your electronics projects. With its USB-C connectors, this switch provides a reliable solution for managing power, featuring a robust digital design from Texas Instruments. It includes a self-resetting 2A fuse for overcurrent protection, input and output LEDs for visual feedback, and an extremely low quiescent current draw to preserve battery life. The switch also supports USB data feed-through, enhancing its functionality.

Ideal for projects with enclosed Thing Plus boards, this power switch offers the convenience of a laptop-style on/off function. A simple press activates the system, while another press, with the help of a microcontroller, can turn it off. In case of any issues, holding the button for about 10 seconds forces a power-down, ensuring safety and reliability.

Connecting the PUSH and OFF pins to a microcontroller allows for monitoring button presses and executing a controlled shutdown sequence. This feature ensures a smooth power-down process, while customizable wake-up and power-down times allow you to tailor the user experience to your specific needs.

The Soft Power Switch's efficient design makes it an excellent choice for battery-powered applications, as it significantly reduces power consumption when idle. Its compact design and USB-C connectors make it easy to integrate into various projects, providing both power management and data connectivity in a single, streamlined package.
