DESCRIPTION
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.
