It handles 1 to 3 series cells with a programmable constant-current charge up to 2 A max and a battery pack voltage ceiling of 15.5 V. The 16 V maximum supply input means it runs cleanly off a 12 V or 15 V wall adapter, but a 24 V industrial rail requires a pre-regulator step. The 2 A charge current is the headline number, but the thermal reality of the 20-VQFN (3.5x4.5) exposed-pad package sets the practical limit. ## Programmable features and fault protection Charge current and charge timer are programmable via external resistors, giving the designer control over the charge profile without I²C or SMBus overhead. The on-chip fault protection covers over-temperature and over-voltage conditions — the part shuts down before the battery or the charger FET sees stress. ## Industrial temperature grade and application fit The multi-chemistry support means it can also handle NiMH or LiFePO4 chemistries with the right termination voltage programming.","metaTitle":"BQ24115RHLR Battery Charger IC, 2A Max, 16V Input, 20-VQFN","metaDescription":"Texas Instruments BQ24115RHLR bqSWITCHER™ multi-chemistry battery charger. 2A programmable charge current, 15.5V pack voltage, 16V input.
