The charge current is set with an external resistor — no I2C or firmware needed, which simplifies the BOM for a dedicated charging rail. The TSOT-23-5 package (2.9 mm × 2.8 mm) keeps the footprint small enough for wearable or portable designs where board area is tight. Surface-mount in a TSOT-23-5 package — the same 5-pin footprint as many other linear chargers, so a layout swap to a pin-compatible alternative is possible without a board spin.","metaTitle":"STC4054GR Li-Ion charger IC, 800mA, TSOT-23-5","metaDescription":"STC4054GR active Li-Ion battery charger IC, 1-cell, 800mA max charge current, TSOT-23-5 package.
