Product Detailed
this parts is new and original,and have stock.

The power select pin, PSEL, defines which input source is to be used first (primary source – AC or USB). If theprimary source is not available, then the IC automatically switches over to the other secondary source if availableor the battery as the last option. If the PSEL is set low, the USB input is selected first and if not available, the ACline is selected (if available) but programmed to a USB input limiting rate (100 mA/500 mA max). This featureallows the use of one input connector, where the host programs the PSEL pin according to what source isconnected (AC adaptor or USB port).The bq24039 has replaced the PSEL pin (node now tied high internally – AC priority) with the ISET3 pin thatallows for twice the standard USB input limiting current levels (200 mA/1000 mA), when set to high. This is afeature for manufacturers that supply their own USB power source that is rated for this higher current level.The bq24038 replaces USBPG with pin VBSEL, to enable user selection of the charge voltage. In addition, pinACPG was modified to PG. PG is active low when either ac power or USB power is detected.The ISET1 pin programs the battery's fast charge constant current level with a resistor. During normal ACoperation, the input supply provides power to both the OUT (System) and BAT pins. For peak or excessive loads(typically when operating from the USB power, PSEL = Low) that would cause the input source to enter currentlimit (or Q3 - USB FET limiting current) and its source and system voltage (OUT pin) to drop, the dynamicpower-path management (DPPM) feature reduces the charging current attempting to prevent any further drop insystem voltage. This feature allows the selection of a lower current rated adaptor based on the average load(ISYS-AVG + IBAT-PGM ) rather than a high peak transient load.
