As a linear topology, it regulates charge current and voltage without a switching inductor — the pass element dissipates the voltage drop as heat, so the board layout needs a good thermal path under the IC. ## Confirming the charge current ceiling before layout For a typical single-cell Li-Ion/Polymer charge profile, the IC terminates at 4.2 V with a constant-current / constant-voltage algorithm; the designer picks the sense resistor value to match the pack's C-rate. Confirm with your EMS that the feeder setup can handle Bulk tubes, or request a reeled variant if the BOM quantity justifies a reel fee. ## Sourcing the BQ2057SNTR against a BOM line The base product number BQ2057 covers multiple package and temperature variants; verify that the suffix SNTR matches your required footprint and operating range before placing the order.","metaTitle":"BQ2057SNTR Texas Instruments Li-Ion/Polymer Charger IC","metaDescription":"Texas Instruments BQ2057SNTR lithium-ion/polymer linear charger IC.
