Battery backup function
The battery switch generally uses its primary battery input B1 as a main power source. If the B1 voltage drops below the configured Voltage threshold value, it can switch to the B2 input. In such a case, the source with a higher voltage will be used. As soon as the B1 voltage returns above the threshold value (+ additional hysteresis), the T70 switches automatically back to B1, no matter the voltage of the B2 input. There are several applications where the user can benefit from the T70:
