Product details

2 A charge ceiling for 1-2 cell Li-Po packs

The BQ24113ARHLT is a TI bqSWITCHER™ series switch-mode charger for Lithium Ion/Polymer batteries, supporting 1 to 2 series cells with a programmable constant-current charge up to 2 A maximum.

Charge current, cell count, and protection set

Charge current is constant and programmable via an external resistor — the 2 A maximum sets the ceiling for a single-cell or two-cell pack. The battery pack voltage for a 2-cell configuration is 8.4 V (4.2 V per cell). Fault protection includes over-temperature and over-voltage, which shuts down the charger if the battery voltage or die temperature exceeds safe limits. Programmable features include charge current and a safety timer — the timer terminates charging if the battery does not reach full voltage within the set window, a useful safeguard for damaged or deeply discharged cells. Supply voltage maximum is 16 V, so the part can be powered from a 5 V USB rail or a 12 V wall adapter without an external pre-regulator.

The base product number is BQ24113, and the 'A' suffix indicates a later revision — the BQ24113A variant is the current production device. For dual-source planning, the BQ24113 and BQ24113A are pin-compatible; the 'A' version typically has tighter regulation accuracy or improved transient response, but both share the same footprint and charge-current range.

Frequently asked questions

What is the maximum charge current for BQ24113ARHLT?

The maximum charge current is 2 A, programmable via an external resistor. The actual charge current is set below this ceiling by the resistor value.

Is BQ24113ARHLT compatible with a single cell LiPo battery?

Yes. The BQ24113ARHLT supports 1 to 2 series cells. For a single-cell LiPo with a 4.2 V termination voltage, configure the cell-count pin for 1-cell operation.

What is the difference between BQ24113 and BQ24113A?

The BQ24113A is a later revision of the BQ24113 base design. Both are pin-compatible and share the same charge-current range and package. The 'A' version typically includes tighter voltage regulation accuracy and improved transient response. For new designs, the BQ24113A is the recommended variant.
