3 Description

The TPL5010-Q1 Nano Timer is a low power, AECQ100

qualified timer with a watchdog feature ideal for

system wake up in duty cycled or battery powered

applications. In such systems the microcontroller

timer can be used for system wake-up, but if the

timer sleep current is high, up to 60-80% of the total

system current can be consumed by the

microcontroller timer in this sleep mode. Consuming

only 35 nA, the TPL5010-Q1 can replace the

functionality of the integrated microcontroller timer

and allow the microcontroller to be placed in a much

lower power mode. Such power savings extend the

operating life of batteries and enable the use of

significantly smaller batteries making the TPL5010-

Q1 ideal for power sensitive applications.. The

TPL5010-Q1 provides selectable timing intervals from

100 ms to 7200 s and is designed for interrupt-driven

applications. Some standards (such as EN50271)

require implementation of a watchdog for safety and

the TPL5010-Q1 realizes this watchdog function at

almost no additional power consumption. The

TPL5010-Q1 is available in a 6-pin SOT23 package.
