Product details

1.5 A single-cell Li-ion charger with USB input

The Texas Instruments BQ24035RHLR is a linear battery charger from the bqTINY™ III series, designed for single-cell Lithium-Ion or Lithium-Polymer packs. The 16 V maximum supply voltage gives headroom for 5 V USB or higher-voltage wall adapters without an external pre-regulator.

Charge current and thermal design

The 1.5 A maximum charge current is programmable via an external resistor, letting you set the charge rate to match the battery capacity and thermal budget.

Protection and programmable features

Built-in fault protection covers over-temperature, reverse current, and short-circuit conditions — the charger shuts down or limits current automatically without external monitoring. The programmable timer sets a safety timeout for the charge cycle, and the current-programming resistor also sets the termination threshold. These features reduce the external component count to a few resistors and capacitors around the 20-VFQFN package.

Frequently asked questions

What is the maximum charge current of BQ24035RHLR?

The maximum charge current is 1.5 A, programmable via an external resistor. The actual current set in the design should account for the thermal dissipation in the linear pass element at the chosen input voltage.

Is BQ24035RHLR compatible with 2-cell batteries?

No. The BQ24035RHLR is designed for single-cell (1-cell) Lithium-Ion or Lithium-Polymer batteries only, with a fixed 4.2 V battery regulation voltage. It cannot charge a 2-cell pack.

Can BQ24035RHLR replace BQ24035RHLT?

The BQ24035RHLR and BQ24035RHLT share the same base product number BQ24035 and the same electrical specifications. The difference is in the packaging and reel options — the RHLR suffix indicates Tape & Reel packaging, while the RHLT suffix indicates a different reel or cut-tape variant. They are functionally interchangeable, but verify the reel quantity and packaging format for your assembly line.
