TPL5010-Q1 - AEC-Q100 Nano-Power System Timer with Watchdog Function

The TPL5010-Q1 Nano Timer is a low power, AEC-Q100 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.
