I am looking to implement the bq24075-Q1 (datasheet) for a school project. This IC can charge a LiPo while simultaneously proving power to the system. The Absolute Maximum ratings sais that the maximum output current is 5 Amps and the maximum charging current is 1.5 Amps. Would I be correct to assume the following:
1) If my system has no battery connected the bq24075-Q1 can pass through 5 Amps to my system.
2) If a battery is connected and charging at the max rate the bq24075-Q1 can pass through 3.5 Amps to the system while still charging the battery at 1.5 Amps
3) There is no current limit on the "OUT" pin. Imagine if the "IN" current can provide a max of 3 Amps (say that is the limit of the wall-wart) and the battery is fully charged. If the System tries to draw 6 amps what will happen? Will 3 Amps be sourced from the "IN" pin and 3 Amps from the "BAT" pin and the IC will overheat and fail?
Thanks in advance for your help!
