TPL5111 Ultra-Low Power System Timers

Texas Instruments TPL5111 Ultra-Low Power System Timers are is ideal for power gating in duty-cycled or battery powered applications. Consuming only 35nA, the TPL5111 can be used to enable and disable the power supply for a microcontroller or other system device. This drastically reduces the overall system standby current during sleep time. This power-saving enables the use of significantly smaller batteries and makes the TPL5111 well suited for energy harvesting or wireless sensor applications. The TPL5111 provides selectable timing intervals from 100ms to 7200s. These TPL5111 timers have a unique one-shot feature where the timer will only assert its enable pulse for one cycle.
