Its 40 V maximum supply voltage accommodates 12 V and 24 V battery banks with enough headroom for the rectified input from a wall adapter or alternator. The part operates over a -40°C to 70°C junction temperature range, which covers outdoor telecom cabinets, uninterruptible power supply (UPS) enclosures, and automotive auxiliary charger applications without requiring a separate thermal management component. ## SOIC-16 footprint and supply rails The wide-body SOIC-16 footprint is common for medium-power analog controllers and supports standard reflow profiles. The supply input is rated up to 40 V, so the designer should place a 40 V or higher-rated input capacitor close to the VCC pin.","metaTitle":"TI BQ24450DWTR Lead-Acid Battery Charger IC, 40V Max","metaDescription":"Texas Instruments BQ24450DWTR lead-acid battery charge controller. 40V supply max, -40°C to 70°C temp range, 16-SOIC.
