TPL5000DGST

The TPL5000DGST is a nano-power Programmable Timer with watchdog functionality. It is optimized for low-power applications. The TPL5000 can replace a micro controllers (µC) internal timer, allowing the µC to stay in low-power sleep mode instead of running a timer, providing a total power consumption reduction of 60 to 80%. It is designed for use in interrupt-driven applications and provides selectable timing from 1 to 64 seconds. Some standards (such as EN50271) require implementation of a watchdog function for safety. It realizes this watchdog function without consuming additional power. It can also monitor a battery management IC via a power-good digital input and reset the microcontroller, if necessary.
