3 Description

The TPL5111 Nano Timer is a low-power system

timer designed 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 standby

current during the sleep time. This power saving

enables the use of significantly smaller batteries 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.
