1 / 8 page FEATURES • Protects Sensitive Lithium-Ion Cells Form Over Charging and Over Discharging • Dedicated for One Cell Applications • Does Not Require External FETs or Sense Resistors • Internal Precision Trimmed Charge and Discharge Voltage Limits • Extremely Low Power Drain • Low FET Switch Voltage Drop of 150mV Typical for 3A Currents • Short Circuit Current Protection (with User Programmable Delay) • 3A Current Capacity • Thermal Shutdown • User Controlled Enable Pin Single Cell Lithium-Ion Battery Protection Circuit BLOCK DIAGRAM UDG-98050 UCC3958 -1/-2/-3/-4 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. 6/98 |
