Product details

The USB interface accepts power from a standard USB port. The 1.5A max charge current is the peak rate the IC can deliver; the actual rate is set by the external programming resistor. Programmable features include charge current and timer. Fault protection covers over-temperature, over-voltage, reverse current, and short circuit — this is the full set of safeguards needed to prevent thermal runaway or damage from a faulty battery pack or input supply.

The base product number is BQ24079, so any PCN or EOL notifications will reference that base.

Frequently asked questions

Is BQ24079RGTR RoHS compliant?

Yes, it is ROHS3 compliant per the lifecycle record.

Can BQ24079RGTR charge two cells?

No — it is a single-cell charger (number of cells: 1) with a battery pack voltage of 4.1V, which is a single Li-Ion cell voltage. For two cells you would need a different charger IC.
