Product details

2.5A single-cell Li-ion charger with integrated protections

The BQ24278RGET: The 2.5 A charge current supports portable devices with single-cell Li-ion packs. On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions, which means the BOM can skip a separate charger front-end protector for many designs.

Supply voltage and battery pack compatibility

Maximum supply voltage is 10 V, so the part can be powered from a standard USB bus or a wall adapter without a pre-regulator. The battery pack voltage is specified at 3.7 V.

Package and thermal design note

Frequently asked questions

What is the maximum charge current of BQ24278RGET?

The maximum programmable charge current is 2.5 A. The charge current is constant and programmable, so you set the rate with an external resistor.

Is BQ24278RGET compatible with a 3.7V Li-ion battery?

Yes. The battery pack voltage is specified as 3.7 V, which is the nominal voltage of a single-cell Li-ion cell. The charger chemistry is Lithium Ion for a single cell.
