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.
