Hi Sir!

I wanna make a usb host device (android , ios / smart device usb power).

Hi ,
Why you set R4H,R5H,R7H and R8H in the circuit ?
I think you needn't to add these resistor since device can output some signal in the DP and DM for hand shake with Phone for charing .

Hi

if it can use tps2514, resistors are not necessary.
it's a spare for removed tps2514.
I do not want to use it if possible.(tps2514)
thank you
