PRELIMINARY

Single Cell Lithium-Ion Battery Protection Circuit

FEATURES

DESCRIPTION

• Protects Sensitive Lithium-Ion Cells Form

Over Charging and Over Discharging

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.

• 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
