FUNCTION
Charge Protection Control Output. Controls an external P-channel high-side charge
protection FET.
Battery Pack Positive Terminal Input. The DS2762 monitors the pack plus terminal
through PLS to detect overcurrent and overload conditions, as well as the presence of a
charge source. Additionally, a charge path to recover a deeply depleted cell is provided

PLS
from PLS to V DD . In sleep mode (with SWEN = 0), any capacitance or voltage source
connected to PLS is discharged internally to V SS through 200 μ A (nominal) to assure
reliable detection of a valid charge source. For details of other internal connections to
PLS and associated conditions see the Li+ Protection Circuitry section.

Data Input/Out. 1-Wire data line. Open-drain output driver. Connect this pin to the DATA
terminal of the battery pack. Pin has an internal 1 m A pulldown for sensing disconnection.
Current-Sense Input. This pin is internally connected to SNS through a 4.7k W resistor.
Current-Sense Input. This pin is internally connected to V SS through a 4.7k W resistor.
Connect a 0.1 m F capacitor between IS1 and IS2 to complete a lowpass input filter.
Power Switch Sense Input. The device wakes up from sleep mode when it senses the
closure of a switch to V SS on this pin. Pin has an internal 1 m A pullup to V DD .
Device Ground. Connect directly to the negative terminal of the Li+ cell. For the external
sense resistor configuration, connect the sense resistor between V SS and SNS.
Programmable I/O Pin. Can be configured to be used to control and monitor user-
