The UCC3952 is a monolithic BiCMOS lithium-ion battery protection circuit that is designed to enhance the useful operating life of one cell rechargeable 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 discharged.  Additional features include an on chip MOSFET for reduced external component count and a charge pump for reduced power losses while charging or discharging a low cell voltage battery pack. This protection circuit requires one external capacitor and is able to operate and safely shutdown in the presence of a short circuit condition.
