The TPL5111 Nano Timer is a low-power system timer designed for power gating in duty cycled or battery-powered applications. Consuming only 35 nA, the TPL5111 can be used to enable and disable the power supply for a micro-controller or other system device, drastically reducing the overall system stand-by current during the sleep time. This power saving enables the use of significantly smaller batteries for energy harvesting or wireless sensor applications. The TPL5111 provides selectable timing intervals from 100 ms to 7200 s. In addition, the TPL5111 has a unique one-shot feature where the timer will only assert its enable pulse for one cycle. The TPL5111 is available in a 6 - pin SOT23 package.
