DETAILED PIN DESCRIPTION
– Table 1
SYMBOL
DESCRIPTION
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.
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
μ
A 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.
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
μ
A 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
resistor.
Connect a 0.1
μ
F 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
resistor.
CC
DC
