description
The UCC3952 monolithic BiCMOS lithium鈥搃on
battery protection circuit increases the useful
operating life of a one-cell rechargeable battery
pack. Cell protection features include 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 compo-
nent 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 can operate
and safely shut down in a short circuit condition.
