Major Chips Description 2-73Table 2-8T62.036.C Pin Descriptions

Pin Name Pin Type Pin No. Description

indicate the current drawn from the AC adapter or other power

source such as docking station power supply. This level is 2

Amps per volt nominal. The source impedance is less than 1KΩ.

CHARGSP I14 Analog input from the system board to limit the total current

consumed by the system from the AC adapter. This signal shall

be compared by the module with the CHARGFB from the system

mother board and the battery charger output current adjusted

until CHARGFB does not exceed CHARGSP. The system board

generates CHARGESP in conjunction with a ID resistor

embedded in the LCD cable. The scale is 2 amps per volt. The

source impedance is less than 2KΩ.

Note: The battery charger output may be reduced below the

level of CHARGESP by the battery charger current limit signal

CHARGECL.

GND GND 15, 16 Ground

CHRGOUT I17, 18,

19, 20 Battery charger current source output at 3.5A max. The output

current is controlled by two control signals which limit the battery

charging current and AC adapter output current. The output

voltage is limited to 13.2V~13.5V.

CN2 signals

P12VR O1, 2 +12V output, 0~0.5A.

GND GND 3, 4, 15,

16 Ground

P3VR O5, 6, 7, 8 +3.3V output, 0~3A.

BMCVCC O11, 13 +5V output, 0~0.5A. Used for resuming from suspend-to-

memory mode.

P3VRON O12 Enables P3VR. Logic level, Active high, +/-luA max loading

P5VRON O14 Enables PSVR. Logic level, Active high, +/-luA max loading

P5VR O17, 18,
