MPS DELAY
A capacitor between this pin and ground sets the delay of the MPS risetime. See MPS
DELAY description in Typical Application section.
Bi-directional logic pin. If driven high by an external source, indicates that a battery is
powering the power bus. If driven high by the AIC, indicates the adapter is powering the
bus. AIC cannot drive MPS low. If there is no valid adapter voltage present, the pin is not
an output but a high impedance logic input. The input is pulled-down via an internal 40k
resistor.
Logic input pin. Active high. Grants permission to the adapter to drive both the power bus
and the MPS signal.
Logic output pin. High when 12 volts

17 volts. The output typically has 40k
pull-down resistor. The source current is not internally limited and the part can be
damaged if the output is shorted to ground when driven HIGH.
