Load Switch Based Ship Mode Reference Design for Wearables

TIDA-00556

Design files

Overview

The TIDA-00556 is a low power, space saving "ship mode" reference design targeted specifically for wearables and other small portable electronics that can be implemented with a simple, low cost load switch.

Features
  • Small solution size of 1.89mm2 fits easily into any design
  • 0.5µA shutdown current during low-power state extends shelf life for a seamless out-of-box experience
  • Component count of 4 keeps BOM costs low and enables scalability across multiple platforms
  • Circuit design is tested and includes board files as well as a design guide

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
