The TPL5000 is a long-term timer IC optimized for low-power applications. The TPL5000 can replace a micro controller–s (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%. The TPL5000 is designed for use in interrupt-driven applications and provides selectable timing from 1 second to 64 seconds. Some standards (such as EN50271) require implementation of a watchdog function for safety. The TPL5000 realizes this watchdog function without consuming additional power. The TPL5000 can also monitor a battery management IC via a power-good digital input and reset the microcontroller, if necessary. The device is packaged in a 10-pin VSSOP package.
