It integrates over-temperature and short-circuit fault protection, and offers programmable charge current and timer via external components. ## Sourcing an obsolete part – what to expect The part is supplied in Tape & Reel (TR) packaging, surface-mount, in the 8-HVSSOP package. ## Key parametric decisions for the BOM The 500 mA maximum charge current sets the charging speed for a single-cell Li-ion pack; if the application requires faster charging, a higher-current charger must be selected. The 4.1V battery regulation voltage is lower than the typical 4.2V termination for standard Li-ion cells, so the battery will not reach full capacity — confirm that the system can tolerate a reduced state of charge. The maximum supply voltage of 13.5V gives headroom for 5V USB or 12V wall-adapter inputs, but the linear topology means that higher input-to-battery differentials increase thermal dissipation in the exposed-pad package.","metaTitle":"BQ24203DGNR Texas Instruments Li-Ion Charger – Obsolete","metaDescription":"Texas Instruments BQ24203DGNR single-cell Li-Ion/Polymer charger, 500 mA max charge current, 4.1V battery voltage, -40°C to 125°C, obsolete.
