Hai,
i would like to have some information about this component TXS4558.
We used TXS4558 IC for interfacing dual sim operation in q2686 module.Still it was not working.
We brought
Vcc=3.3V, VBat=4.1V,
VSEL1=0,VSEL2=0
CLKRUN1=1,CLKRUN2=1
But we had received
O/P Sim voltage was VSIM1=2.3V, VSIM2=2.3V respect to enable EN1,EN2.
We dont Know ,why was VSIM voltages more than 1.8V?
Plz Guide me for configuration for Sim Switching
Regards
Sam
