The TPL5111 Nano Timer is a low-power system timer designed for power gating in dutycycled or battery-powered applications. Consuming only 35 nA, the TPL5111 can be used to enable anddisable the power supply for a micro-controller or other system device, drastically reducing theoverall system stand-by current during the sleep time. This power saving enables the use ofsignificantly smaller batteries for energy harvesting or wireless sensor applications. The TPL5111provides selectable timing intervals from 100 ms to 7200 s. In addition, the TPL5111 has a uniqueone-shot feature where the timer will only assert its enable pulse for one cycle. The TPL5111 isavailable in a 6 -
pin SOT23 package.
