Enhanced Single Cell Lithium-Ion Battery Protection IC

FEATURES

DESCRIPTION

• Protects sensitive Lithium Ion cells

from over-charging and

over-discharging

The UCC3952 is a monolithic BiCMOS lithium-ion battery protection circuit

that is designed to enhance the useful operating life of one cell recharge-

able battery pack. Cell protection features consist of internally trimmed

charge and discharge voltage limits, discharge current limit with a delayed

shutdown and an ultra low current sleep mode state when the cell is dis-

charged. Additional features include an on chip MOSFET for reduced exter-

nal component count and a charge pump for reduced power losses while

charging or discharging a low cell voltage battery pack. This protection cir-

cuit requires one external capacitor and is able to operate and safely shut-

down in the presence of a short circuit condition.

• Dedicated for one cell applications

• Integrated low impedance MOSFET

switch and sense resistor

• Precision trimmed overcharge and

overdischarge voltage limits

• Extremely low power drain

• 3A current capacity

• Overcurrent and Short Circuit

Protection

• Reverse Charger Protection

• Thermal Protection
