Working Principles

The TPL5110DDCR operates as a low-power timer, controlling the power cycles of a device. When the EN pin is pulled high, the timer starts counting based on the delay time set using the DELAY pin. After the programmed delay, the VOUT pin switches from low to high, enabling the device connected to it. When the EN pin is pulled low, the timer stops counting and the VOUT pin switches back to low, disabling the device.
