I bought two TPS2540EVN-623 boards with TPS2540 chip loaded recently. According to TPS2540 datasheet, page 26, TPS2540 control truth table, when CTL1-3 are '1', the chip supports Charging Downstream Port, BC1.2. But in the TPS2540EVN-623 board User Guide, page 6, Table 4, it says when CTL1-3 are '1', it supports Charging Downstream Port, BC Specification1.1.
I tested TPS2540EVN-623 with Samsung S4 and I can only get about 900mA into the phone maximum. this matches with the BC1.1 as specified by the TPS2540EVN-623 board User Guide. is this correct? is it possible to charge S4 or S5 with 1.5A using TPS2540? Thanks very much
