Hi Julian,

I will recommend you to consider using the TXS02326A device which has automatic SIM card detect.

Hi Julian,

"The TXS02326A also includes a shutdown input and a comparator input that detects battery pack removal to safely power-down the two SIM cards."
The device control register has the control over the shutdown detection as listed in page 4.
Table 10 in page 8 shows the device control register setting for each bit.

Hi Shreyas,

Sorry that let you misunderstanding my qustion.

Our customer just want to know the SIM Card had plugged in or not.

(IF SIM1 don't plug in but SIM2 had, circuit will switch to SIM2)

Could TXS02324 support the function that report the SIM card status for plugin or not?

I find the REG[04] maybe can show it, but I'm not sure.

Hi Julian,

Page 7 and page 8 discusses the operation and switching between the 2 SIM cards.
This device doesnt have automatic SIM card detect but needs to be configured to switch between either of the 2.
After power up, the SIM1 is selected by default.
