DETAILED PIN DESCRIPTION
SYMBOL
DESCRIPTION
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. Connect PLS to the pack positive terminal
through a 100 resistor.
Power-Switch Sense Input.
The device wakes up from sleep mode when it senses the
closure of a switch to V
SS
on this pin.
PS
has a high-impedance internal pullup.
Data Input/Out.
1-Wire data line. Open-drain output driver. Connect this pin to the
DATA terminal of the battery pack. DQ has an internal 0.5 A pull-down.
V
SS
Device Ground.
Connect directly to the negative terminal of the battery cell.
Power Supply Input.
Connect V
DD
to the positive terminal of the battery cell through a
decoupling network.
Charge Pump Output.
The internal charge pump regulates CP to 9V which supplies
the ON state drive to the protection FETs. Connect a 0.1 F reservoir capacitor from CP
to V
SS
.
Charge Protection Control Output.
Controls an external N-channel high-side charge
protection FET.
Discharge Protection Control Output.
Controls an external N-channel high-side
discharge protection FET.
