3 Description
The TPL5111 Nano Timer is a low power system
timer, ideal 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 and
makes the TPL5111 well suited 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.
