TPL5111DDCT

TEXAS INSTRUMENTS  TPL5111DDCT  芯片, 系统定时器, 单路, 5.5V, SOT-23-6

The is a nano-timer 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 micro-controller or other system device, drastically reducing the overall system standby current during the 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. It provides selectable timing intervals from 100ms to 7200s. In addition, it has unique One-shot feature where the timer will only assert its enable pulse for one cycle.
