Name
Function
1
MPS DELAY
A capacitor between this pin and ground sets the delay of the MPS risetime. See MPS
DELAY description in Typical Application section.

MASTER POWER
SOURCE
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.
3
ADAPTER
ENABLE
Logic input pin. Active high. Grants permission to the adapter to drive both the power bus
and the MPS signal.
4
ADAPTER
PRESENT
Logic output pin. High when 12 volts < V
ADAPTER < 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.
5
CHARGER
PRESENT
Logic output pin. High when V
ADAPTER > 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.
9
GND
IC ground pin.
10
DISCONNECT
Drives the gate of the disconnect P-ch FET.
11
BACKFEED
Drives the gate of the backfeed P-ch FET.
12
DIRECTION
SENSE
Connection for current sense resistor to control BACKFEED.
13
PEAK SENSE
Connection for current sense resistor to control DISCONNECT.
14
V
ADAPTER
Power input pin. Output of AC adapter, auto adapter or airline adapter.
