    Yes, the bq24052 can just power the system without a battery being installed. This is called TTDM and is explained on page 24 of the datasheet. The ISET2 pin has 3 different states--high, low, and floating. Each of these states gives a different charge…

    Srinivas, The bq24050 and bq24052 are priced the same and availability will be similar. What charge current do you need? If ISET2 = GND, then the resistance on ISET programs the current. When VIN is not applied, the charger is off and cannot monitor…
