What the 17V input ceiling means for your power rail
The BQ24130RHLT accepts a maximum supply voltage of 17V, which covers common input sources like a 5V USB port, a 9V wall wart, or a 12V adapter — but not a 24V industrial rail without a front-end buck or clamp. With 1-3 cell support and a battery pack voltage ceiling of 12.6V, this part fits 3S Li-ion, 2S Li-Po, or single-cell LiFePO4 stacks. A 4S pack at 16.8V exceeds the rating — you'd need a different charger IC. The constant-current charging mode is programmable, so you set the charge current with an external resistor — the datasheet typical application shows a 10 kΩ resistor for 1 A, but the actual current limit depends on the sense resistor and thermal budget.
Temperature range and thermal reality in the 20-VQFN
That means you can commit this part to a production BOM without stockpiling or qualifying a second source for the next 12-18 months. ROHS3 compliant — no lead-free exemption issues for EU or California market shipments.
Surface-mount in a 20-VFQFN exposed-pad package, supplier device package 20-VQFN (3.5x4.5). The 0.50 mm pitch QFN requires a solder-paste stencil with 0.25 mm apertures and a reflow profile peaking at 260°C peak for lead-free solder. Without it, the charger may throttle current or trip over-temperature protection during a full charge cycle.
