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 device monitors the state of
the battery pack’s positive terminal through this pin in order to detect
events such as the attachment of a charger or the removal of a short
circuit. Additionally, a charge path to recover a deeply depleted cell is
provided from PLS to VDD.

E4
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.
