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.
