Ultra low-power timer with watchdog functionality and manual reset

The Texas Instruments (TI) TPL5010 Nano Timer is an ultra low-power timer with a watchdog feature ideal for system wake up in duty cycled or battery powered applications. In such systems the device can be used for system wake-up, but if the timer sleep current is high, up to 60-80% of the total system current can be consumed by the timer in this sleep mode. Consuming only 35nA, the TPL5010 can replace the functionality of the integrated µC timer and allow it to be placed in a much lower power mode. Such power savings enable the use of significantly smaller batteries making it well suited to energy-harvesting or wireless sensor applications.
