Other Parts Discussed in Thread: TMUX1574
Hi,
My customer use TS3A27518E for SD card, if run PASSMARK Burn in SD card test item, got 100% fail (can't access SD card) with UHS-I (SDR104 ) card
We wonder it might be caused by the total load capacitance over Spec. which is 40pF for the Max. value( host – PCB trace – switch – ESD diode –SD card slot –SD card )
For TS3A27518E switch’s load capacitance is around 21.5pF, is there a lower load capacitance switch solution can replace TS3A27518E?
Or you have any suggestion for the issue?
