3 Description
The TPL5110 Nano Timer is a low power timer with
an integrated MOSFET driver ideal for power gating
in duty cycled or battery powered applications.
Consuming only 35nA, 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 making it well suited for energy harvesting
or wireless sensor applications. The TPL5110
provides selectable timing intervals from 100ms to
7200s 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.
