GE865: Current split between VBAT and VBAT_PA inputs pins

One thought on “GE865: Current split between VBAT and VBAT_PA inputs pins

  1. We would like to size properly the capacitors on the VBAT and VBAT_PA lines.

     

    We understand that the GE865 can use 2A peak with GPRS Class10.

     

    But what is the current consumption split between the VBAT and VBAT_PA, please?

     

    For best power supply design, we use separated power lines for VBAT_PA and VBAT.

     

    If the VBAT pin uses less than 100mA max then the VBAT need less decoupling and the VBAT_PA more decoupling if most of the 2A peak  is used by the power amplifier.
