<p>➀ TI's TIDA-00556 reference design implements a compact "ship mode" using the TPS22916B load switch to minimize battery drain during storage/shipping for wearables; </p><p>➁ The solution achieves ultra-low shutdown current (10nA), a 1.89mm² footprint, and 60mΩ MOSFET resistance, ideal for space-constrained devices;</p><p>➂ By cutting off power via emulated GPIO signals, it extends battery shelf life and supports operation across 2.7V-4.35V input ranges for wearables like smartwatches and medical devices.</p>
