C1

Charge Protection Control Output. Controls an external p-channel

high-side charge protection FET.

DC

3

B2

Discharge Protection Control Output. Controls an external p-channel

high-side discharge protection FET.

DQ

7

B4

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

mA pull-down for sensing disconnection.

PIO

14

E2

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

external circuitry. Open drain to VSS.

PLS

2

B1

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.

PS

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

VIN

16

D1

Voltage Sense Input. The voltage of the Li+ cell is monitored via this

15

E1

Power Supply Input. Connect to the positive terminal of the Li+ cell

through a decoupling network.

VSS

11,12,13

F3

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.

SNS

4,5,6

A3

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

9

D4

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

4.7k

W resistor. Connect a 0.1mF capacitor between IS1 and IS2 to

complete a low-pass input filter.

IS2

8

C4

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

4.7k

W resistor.
