PRELIMINARY
DESCRIPTION
UCC3958 is a monolithic BCMOS lithium-ion battery protection
circuit that is designed to enhance the useful operating life of
one cell rechargeable battery packs. Cell protection features
consist of internally trimmed charge and discharge voltage lim-
its, discharge current limit with a delayed shutdown and an ultra
low current sleep mode state when the cell is discharged. Addi-
tional 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 circuit requires a minimum number of ex-
ternal components and is able to operate and safely shutdown
in the presence of a short circuit load.
