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.
