8.1 Application Information

In battery-powered applications one design constraint is the need for low current consumption. The TPL5111 is suitable in applications where there is a need to monitor environmental conditions at a fixed time interval, but at a very low rate. In these applications a watchdog or other internal timer in a µC is often used to implement a wake-up function. Typically, the power consumption of these timers is not optimized. Using the TPL5111 to implement a periodic power gating of the µC or of the entire system can reduce current consumption to only tens of nA.
