hi

i cant charge the battery in the design below i dont see the problem ?

input 5v 

TS is disabled in 10k to DRV voltage

CE is drive to low in 10k pull down

Iset is set to 400Ohm -> 2A 

the load conductor is connectted but no load 

1- CAN USB1/2/3 float in case (or do i need to configured to high impedance)

    The DRV capacitor needs to be at least 2.2uF. There needs to be at least 20uF total capacitance on SYS pin and 1uF on BAT. The IUSBx pins set the input current as explained in Table 1 on page 21 of the datasheet. For 2-A charge current, you will need to set the input current limit to 2500mA.
