In cases where both supplies are connected, they must remain isolated from each other which means only one is allowed to charge the battery. Write a “1” to SUPPLY_SEL to select the USB input to have precedence. Write a “0” to select the IN input.Note the following behavior when switching the SUPPLY_SEL bit with both supplies attached: • The bq2416xx returns to high impedance mode • The input supply is switched • The bq2416xx begins a full startup cycle starting with bad adapter detection then proceeding to soft-start Similarly, if charging from the non-preferred supply when the preferred supply is attached, the bq2416xx follows the same procedure. STAT_x and FAULT_x Bits The STAT_x show the current status of the device and are updated dynamically as the IC changes state. The FAULT_x bits show faults that have occurred and are only cleared by reading the bits, assuming the fault no longer exists. If multiple faults occur, the first one is the one that is shown. 9.6.2 Battery/ Supply Status Register (READ/WRITE) Memory location: 01, Reset state: xxxx 0xxx BIT NAME Read/Write FUNCTION B7 (MSB) INSTAT1 Read Only 00-Normal 01-Supply OVP 10-Weak Source Connected (No Charging) 11- VIN<VUVLO B6 INSTAT0 Read Only B5 USBSTAT1 Read Only 00-Normal 01-Supply OVP 01-Weak Source Connected (No Charging) 11- VUSB<VUVLO B4 USBSTAT0 Read Only |
