APPLICATION
1.
Method of Using the CONTROL Pin
It is possible to control the operation of analog switch 1 by entering a High or Low level to the CONTROL pin while
being powered by the battery. The Table below shows how the analog switch operates when its operation is controlled
from the CONTROL pin.
When using the primary and the secondary batteries in combination as in the case of memory cards, be sure to
set the CONTROL pin High to prevent the primary battery from being recharged by the secondary battery current
flowing from analog switch 1.
Control Conditions of CONTROL Pin
*1: If the CONTROL pin is released open, the logic state of the CMOS circuit may become instable letting current
flow into the circuit. Therefore, the CONTROL pin must always have a High or Low level input.
*2: The ON-resistance of the analog switch is approximately 10 K ohms.
