RL78/G1C USB BC 1.2 issues

Hi,

Is it possible to have communication over usb ,as CDP,at high current rates ,say about 650mA above.We are using BC 1.2 specification.

  • Hi Reema,

    Maybe this blog renesasrulz.com/.../high-speed-battery-charging-via-usb will answer your questions regarding RL78/G1C. Hope it helps!

    Hi JB,
    Thanks for you reply. Our requirement is that our application should be open all the time & communicating with the device connected .If tablet is drawing only 450mA & tablet is on, tablet will get shut down at one point. This should not happen. Our App is open all the time & app will keep on getting data all the time.So the tablet connected to our board should draw higher currents at low battery ,say above 850mA. We are facing an issue ,when tablet draws 450mA the communication is proper.When it draws higher current communication is lost. We are either missing data or there is no data received in the app.

    Reema,

    It appears that your device is entering USB debugging mode.
