Product details

Single-cell Li-ion charger with I²C control

The Texas Instruments BQ24161RGER is a single-cell Lithium Ion/Polymer battery charger in a 24-VFQFN Exposed Pad package, controlled via an I²C interface. It delivers a programmable constant charge current up to 2.5 A max, sized for portable devices that need fast charging without a separate microcontroller PWM pin.

Protection and temperature range

Built-in fault protection covers over-temperature and over-voltage conditions, reducing the external supervisor circuitry the BOM would otherwise need.

Package and supply rails

Maximum supply input is 10 V, so a 5 V USB rail or a 9 V wall adapter fits within the absolute maximum; a 12 V rail would need a pre-regulator.

Frequently asked questions

Does the BQ24161RGER support 2-cell battery packs?

No, the BQ24161RGER is designed for single-cell (1S) Lithium Ion/Polymer packs with a nominal battery voltage of 3.7 V. It does not support 2-cell configurations.
