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.
