The 8.4 V battery pack voltage rating aligns with a standard 2-cell stack, so a 2-cell pack is within the operating envelope — no need to derate or add external balancing. ## Programmable current and timer for charge profile control Charge current and a safety timer are programmable via external components, letting you set the constant-current phase and a backup termination timeout. The 16 V maximum supply voltage gives headroom for common 12 V or 15 V wall adapters without a pre-regulator. ## Active production and package details It ships in Tape & Reel (TR) or Cut Tape (CT) options, surface-mount in a 20-VFQFN Exposed Pad package (3.5x4.5 mm body). ## Fault protection and temperature grade On-chip over-temperature protection shuts down the charger if the die exceeds the safe limit — no external thermistor required for the IC itself.","metaTitle":"BQ24123RHLT – Texas Instruments bqSWITCHER™ Li-Ion Charger","metaDescription":"BQ24123RHLT from TI: 2 A max charge current, 8.4 V battery pack voltage, 1-3 cell Li-Ion/Polymer charger.
