Product details

3 A charge current, I²C-programmable, single-cell Li-ion charger

The BQ24295RGER is a single-cell Li-Ion/Polymer battery charger that delivers up to 3 A of programmable charge current from a USB or I²C-controlled input, housed in a 24-VFQFN exposed-pad package (4x4 mm).

Fault protection and temperature range

Built-in fault protection covers over-current, over-temperature, and over-voltage conditions — these are safety features that prevent runaway charging if the cell or input rail goes out of bounds.

Active production and compliance

The part is ROHS3 Compliant per the manufacturer's declaration, which covers the EU RoHS exemption list through 2024.
