Chip also simultaneously closes off its lower secondary power supply hung after receiving power-off signal, and is transmitted down power-off signal by GPIO
It goes, until each power monitoring chip has received power-off signal by GPIO, closes all secondary power supplies, waiting re-powers.
As long as all power monitoring chips can receive power-off signal, and then close institute so power down occurs in one of primary power source
There is secondary power supply, waiting re-powers.
Each power monitoring chip is connected to carry out the transmitting of power-off signal by GPIO, and the succession of GPIO can also be with
It is to be connected two-by-two between chip, every two power monitoring chip has 2 GPIO to carry out power-off signal transmitting.But this in Fig. 4
The connection type advantage of the GPIO of kind annular is: ensure that each power monitoring chip can receive the premise of power-off signal
Under, effectively save the quantity required of GPIO.
