| Description | The TPL5110QDDCRQ1 is an automotive-grade, nano-power system timer with an integrated MOSFET driver, designed for power-gating applications. It operates within a supply voltage range of 1.8V to 5.5V and consumes a typical current of 35 nA at 2.5V, making it highly energy-efficient. The device offers selectable timing intervals from 100 milliseconds to 7200 seconds, with a typical timer accuracy of 1%. It features a resistor-selectable time interval, manual MOSFET power-on capability, and a unique one-shot function where the timer powers the MOSFET for a single cycle. Qualified for automotive applications, the TPL5110QDDCRQ1 meets AEC-Q100 standards, operating over a temperature range of -40°C to 125°C. It is available in a compact 6-pin SOT-23 package. |

How it works, in short:
-
You connect the system's power supply through the TPL5110.
-
It acts like a smart switch.
-
-
The TPL5110 turns ON the system at a set interval (adjustable via a resistor or jumper).
-
This is the timer interval (from ~100ms to 2 hours).
-
-
Your system does its job (e.g., read sensor, transmit data), then signals the TPL5110 it's done by pulling the DONE pin high.
-
TPL5110 cuts the power, putting the whole system to sleep until the next interval.
Key Pins:
-
VDD – Power to the timer itself.
-
DRIVE – Output to power your system (goes high when ON).
-
DONE – Your system pulls this HIGH to say "I’m finished."
-
DELAY/MODE – Sets the timer interval using a resistor.
Why use it?
It draws very little current (~30nA) when waiting, making it perfect for battery-powered projects.
