Charge Protection Control Output. Controls an external p-channel
high-side charge protection FET.
Discharge Protection Control Output. Controls an external p-channel
high-side discharge protection FET.
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 pull-down for sensing disconnection.

B1
Programmable I/O Pin. Used to control and monitor user-defined
external circuitry. Open drain to VSS.
Battery Pack Positive Terminal Input. The DS2761 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 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 m 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.

Power Switch Sense Input. The device wakes up from Sleep Mode
when it senses the closure of a switch to VSS on this pin. Pin has an
internal 1 m A pull-up to V DD .

Power Supply Input. Connect to the positive terminal of the Li+ cell
through a decoupling network.
Device Ground. Connect directly to the negative terminal of the Li+ cell.
For the external sense resistor configuration, connect the sense resistor
between VSS and SNS.
