Texas Instruments TPL5010/TPL5010-Q1 Nano-Power System Timers
Texas Instruments TPL5010/TPL5010-Q1 Nano-Power System Timers are low-power timers with a watchdog feature ideal for system wake up in duty-cycled or battery-powered applications. In such systems the µC 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 µC timer in this sleep mode. Consuming only 35nA, the TPL5010/TPL5010-Q1 can replace the functionality of the integrated μC timer and allow the µC to be placed in a much lower power mode. Such power savings enable the use of significantly smaller batteries making it well suited for energy harvesting or wireless sensor applications.
TI TPL5010 provides selectable timing intervals from 100ms to 7200s and is designed for interrupt-driven applications. Some standards (such as EN50271) require implementation of a watchdog for safety and the TPL5010 realizes this watchdog function at almost no additional power consumption. The TPL5010-Q1 devices are AEC-Q100 qualified for automotive applications.
