Charge termination voltage is fixed at 4.2 V per cell, and the IC includes over-temperature and short-circuit fault protection. Programmable features are limited to charge current and timer – no I²C or SMBus interface, so the charge profile is set by external resistors and the timer pin. ## Obsolete – plan your BOM around independent supply For a production BOM that cannot requalify, the only sourcing path is through independent distribution or the spot market. We can source and quote to order against your quantity – confirm availability and current pricing at quote time. The base product number BQ24204 suggests that other suffix variants (e.g., BQ24204DGNR) share the same die but differ in packaging or tape/reel orientation – verify mechanical compatibility before substituting. ## Thermal and layout – the exposed pad is your heatsink The 8-HVSSOP package (3.00 mm width, exposed pad) requires a thermal land on the PCB connected to a copper plane; without it, the 500 mA charge current will push junction temperature above the 125°C absolute maximum in still air. Supply voltage range extends to 13.5 V max. Mounting type is Surface Mount, and the part ships in Tape & Reel (TR) – suitable for automated pick-and-place.","metaTitle":"BQ24204DGNRG4 – TI Li-Ion Charger, 500 mA, Obsolete","metaDescription":"Texas Instruments BQ24204DGNRG4 single-cell Li-Ion/Polymer charger, 500 mA max, -40°C to 125°C, 8-HVSSOP.
