Product details

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.

Frequently asked questions

What is the maximum charge current for BQ24130RHLT?

The charge current is constant and programmable — the datasheet shows a typical range up to 2 A, but the actual limit is set by the external sense resistor and the thermal capability of the 20-VQFN package. For a 1 A design, use a 10 kΩ ISET resistor as a starting point.

Does BQ24130RHLT support Li-Polymer batteries?

Yes — the part is rated for multi-chemistry including Li-Polymer. The 1-3 cell range covers single-cell Li-Po (3.7V nominal) up to 3S Li-Po (11.1V nominal), with a battery pack voltage ceiling of 12.6V.

Is BQ24130RHLT lead-free and RoHS compliant?

Yes — it is ROHS3 compliant, meaning no restricted substances above the threshold limits, including lead, mercury, and cadmium. No exemption applies.
