Pin Description

Pin No.

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.

2

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

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

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.
