UCC3977PW TI Battery Charge Controller | 8-TSSOP | 1-4 Cells, Li-Ion

Product Overview

The UCC3977PW from Texas Instruments is a highly integrated, multi-chemistry battery charge controller designed for 1 to 4 series Li-Ion or Li-Polymer cells. Housed in a compact 8-pin TSSOP package, it provides constant-current/constant-voltage (CC/CV) charging with programmable charge current and voltage. The device features automatic charge termination, preconditioning for deeply discharged cells, and a status output for charge indication. Its low external component count and small footprint make it ideal for space-constrained portable applications.
