3 Description

The TPL5110-Q1 Nano Timer is a low power, AEC-

Q100 qualified timer with an integrated MOSFET

driver ideal for power gating in duty cycled or battery

powered applications. Consuming only 35nA, the

TPL5110-Q1 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-Q1 provides selectable

timing intervals from 100ms to 7200s and is designed

for

power

gating

applications.

In

addition,

the

TPL5110-Q1 has a unique One-shot feature where

the timer will only power the MOSFET for one cycle.

The TPL5110-Q1 is available in a 6-pin SOT23

package.
