SYMBOL

DESCRIPTION

CC

Charge Protection Control Output. Controls an external p-channel high-side charge

protection FET.

DC

Discharge Protection Control Output. Controls an external p-channel high-side

discharge protection FET.

DQ

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

µA pull-down for sensing

disconnection.

PIO

Programmable I/O Pin. Used to control and monitor user-defined external circuitry.

Open drain to VSS.

PLS

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.

PS

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

µA pull-up.

VIN

Voltage Sense Input. The voltage of the Li-Ion cell is monitored via this input pin.

VDD

Power Supply Input. Connect to the positive terminal of the Li-Ion cell through a

decoupling network.

VSS

Device Ground. Connect directly to the negative terminal of the Li-Ion cell. For the

external sense resistor configuration, connect the sense resistor between VSS and SNS.

SNS

Sense Resistor Connection. Connect to the negative terminal of the battery pack. In the

internal sense resistor configuration, the sense resistor is connected between VSS and

SNS.

IS1

Current Sense Input. This pin is internally connected to VSS through a 4.7 k

Ω resistor.

Connect a 0.1

µF capacitor between IS1 and IS2 to complete a low-pass input filter.

IS2

Current Sense Input. This pin is internally connected to SNS through a 4.7 k

Ω resistor.
