The TPL5110 Nano Timer is a low power timer with an integrated MOSFET driver designed for power gating in duty cycled or battery-powered applications. Consuming only 35 nA, the TPL5110 can enable the power supply line and drastically reduce the overall system stand by current during the sleep time. Such power savings enable the use of significantly smaller batteries for energy harvesting or wireless sensor applications. The TPL5110 provides selectable timing intervals from 100 ms to 7200 s and is designed for power gating applications. In addition, the TPL5110 has a unique One-shot feature where the timer will only power the MOSFET for one cycle. The TPL5110 is available in a 6-pin SOT23 package.
