The constant-current charge profile is programmable via external resistors, and the termination voltage is fixed at 4.2V per cell — the standard for 1S Li-ion and Li-polymer packs. ## Charge current and input voltage — sizing the power path With a 16V absolute maximum input, the charger accepts 5V USB, 9V/12V wall adapters, or unregulated 12V rails without an external buck pre-regulator — useful in automotive and industrial designs where the input bus is not tightly regulated. ## Package and footprint — reflow and placement notes The 20-VFQFN with exposed pad (3.5x4.5 mm body) requires a solder-paste stencil aperture covering 50–70% of the pad area to avoid voiding and tombstoning. The MSL rating should be verified before the bake decision.","metaTitle":"BQ24120RHLR Li-Ion Charger, bqSWITCHER, 2A Max, 20-VQFN","metaDescription":"Texas Instruments BQ24120RHLR single-cell Li-Ion/Polymer charger, 2A max charge current, 16V input, -40°C to 85°C, 20-VQFN.
