description  
The UCC3956 family of switch-mode lithium-ion battery-charger controllers accurately control lithium-ion battery  
charging with a highly-efficient average-current-control loop. This chip is designed to work as a stand-alone charger  
controller for a single-cell or multiple-cell battery pack. This chip combines charge-state logic and average-current  
PWM control circuitry with a 14-bit counter to program the overcharge time. The charge-state logic indicates current-  
or voltage-control depending on the charge state. The chip includes undervoltage lockout (UVLO) circuitry to ensure  
sufficient supply voltage is present before output switching starts. Additional circuit blocks include a  
differential-current-sense amplifier, a 1% voltage reference, voltage- and current-error amplifiers, PWM latch,  
charge-state decode bits, and a 500-mA output driver.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and  
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not  
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
Unless otherwise indicated, voltages are reference to ground and currents are positive into and negative out of the specified terminals. Consult  
Packaging Information section of the Portable Products Databook (TI Literature No. SLUD001) for thermal limitations and considerations of  
packages. All voltages are referenced to GND.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
