The TPL5000 can replace a • Current Consumption 30nA (typ, at 2.5V) micro controller's (µC) internal timer, allowing the µC • Watchdog Functionality to stay in low power sleep mode instead of running a timer, providing a total power consumption reduction • Reset Functionality of 60 to 80%. The TPL5000 is designed for use in • Selectable Timer Intervals 1s to 64s interrupt-driven applications and provides selectable timing from 1 second to 64 seconds. Some Standards APPLICATIONS (i.e. EN50271) require implementation of a watchdog function for safety. The TPL5000 realizes this • Battery powered systems watchdog function without consuming additional • Energy harvesting systems power. The TPL5000 can also monitor a battery • Remote data-logger management IC via a power-good digital input and reset the µC if necessary. The device is packaged in • Sensor node a 10-pin VSSOP package. • Building automation • Consumer electronic • Low power wireless • Safety and security platforms Simplified Application Schematic 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
