Product details

2A Li-Ion/Polymer charger in a compact 20-VQFN

The Texas Instruments BQ24113RHLR is a bqSWITCHER™ series Li-Ion/Polymer battery charger IC delivering a programmable constant-current charge up to 2A.

Charge current and thermal design

The 2A maximum charge current is set via an external resistor on the ISET pin, with a programmable timer to terminate the charge cycle. Input supply voltage can go up to 16V, which covers common 5V USB, 9V, or 12V wall adapters. Over-temperature and over-voltage fault protection are integrated, so the charger can operate without an external supervisory IC.

Frequently asked questions

What is the maximum charge current for BQ24113RHLR?

The maximum charge current is 2A, set by an external resistor on the ISET pin. The charger operates in constant-current mode until the battery voltage reaches the regulation target, then transitions to constant-voltage.

Does BQ24113RHLR work with single-cell Li-Po batteries?

Yes, it supports 1 to 2 cells. For a single-cell Li-Po pack (4.2V termination), the battery voltage regulation is set by the external resistor divider on the BAT pin. The charger can also handle 2S packs up to 8.4V.
