It integrates the charge termination logic and a programmable timer and voltage setpoint into a single 8-SOIC package, reducing external component count for a dedicated charger circuit. ## 6V supply ceiling and programmable termination The device operates from a supply up to 6 V, which sets the input voltage headroom for the charging pass element. The programmable timer and voltage features let you tailor the charge termination to the specific cell chemistry — a key parameter for preventing overcharge in NiMH or Li-Ion packs. The 8-SOIC footprint with 0.154-inch body width is a standard outline that routes easily on a two-layer board.","metaTitle":"BQ24400DG4 Multi-Chemistry Battery Charger Controller","metaDescription":"Texas Instruments BQ24400DG4 multi-chemistry battery charge controller.
