BQ24195 EVM connected to USB SDP port.Input current limit is set to 500mA.Fast charge current to 512mA.Then I found currents across PMID=740mA,VSYS=520mA,BAT=472mA.

I have connected 6ohm load across PMID & 6 ohm load across VSYS of BQ24195 EVM and then EVM  to USB port.By default after connecting to USB it is entering into high impedance(HIZ)  state.

Then I wrote

REG00 to 32 to limit input current limit to 500mA &

REG02 to 00 to set fast charge current to 512mA.

Then I found that PMID current =740mA.

VSYS current =520mA

BAT current= 472mA

is it okay  because SDP can source max 500mA.And 500mA not equal to (740+520+472)mA
