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