It delivers a constant programmable charge current — set by an external resistor — making it a straightforward drop-in for portable devices that need a dedicated charge management IC. Packaged in an 8-VSSOP (3.00 mm width, 0.118-inch pitch), this surface-mount part fits compact PCB layouts common in handheld and wearable electronics. The supply voltage range extends to 15V, accommodating typical 5V USB or wall-adapter inputs without an external pre-regulator. ## Obsolete — sourcing through independent channels Buyers with an existing BOM line requiring this exact order code will need to source from independent distribution or broker inventory. The 8-VSSOP package and Tape & Reel (TR) packaging format are standard for this series, but date-code and lot traceability become critical when buying obsolete parts from the open market — a consistent marking font and package seal are the first screen against re-marked or relabeled stock. ## Temperature grade and package fit Rated for an operating temperature range of -20°C to 70°C, this charger suits consumer and commercial environments — indoor portable gear, battery-powered instruments, and handheld tools. The 8-VSSOP footprint is shared with other TI charger controllers, so a board-level swap to a different TI single-cell charger is mechanically feasible if the pinout matches.","metaTitle":"BQ2057PDGKRG4 Obsolete Single-Cell Li-Ion Charger","metaDescription":"Texas Instruments BQ2057PDGKRG4 — single-cell Li-Ion/Polymer charger in 8-VSSOP, 4.1V battery pack voltage.
