Part Number: TIC12400
Greetings, I am using TIC12400 for switch monitoring which is based on Serial Peripheral Interface (SPI). I am facing issues in writing configuration for wetting current and some state machines. I am requesting you to please…
Part Number: TIC12400 Need technical expert recommendation from about TIC12400 for following queries.
Can we read the analog voltage of all input through SPI?
If yes, then can you provide the mode recommendation if I want to read the multiple analog…
Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TCAN1145-Q1 Hello team,
Can you help confirm what is the internal block diagram of SPI signal inside the TIC12400-Q1?
Four signals: CS, SCLK, SDI,SDO, how do they connect each? pull up resistor to…
Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TIC12400 , Hi Team,
The requirement for the resistor coded switch to be interfaced with the MSDI is as follows:
10K when switch not pressed
Press to Ground when the switch is active.
and the wetting…
Part Number: TIC12400-Q1 Hello experts,
I saw there is a RIN,SC input resistance=240kOhm on the page 8 of the datasheet. I suppose this is a pull down resistance right? Should we consider this resistance when we doing the ADC sampling accuracy calculation…
Part Number: TIC12400-Q1 HI Team,
Please clarify my below queries.
I'm using this IC for digital input sensing. In this case , what will be the maximum input current that should be considered for the sinking input and sourcing input?
Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TIC12400 Hello Experts,
I found the internal ADC of TIC12400's reference voltage is marked as 6V, may I know where does this 6V come from? Because I just considered 6V is not a common ref voltage…
Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TIC12400 Hello experts
We used TI's TIC12400 chip. After it was loaded and used for a period of time, a fault occurred. The switch status collected by the 12400 chip could not follow the change.…
Part Number: TIC12400-Q1 Hi,
Tic12400-q1 inx external circuit: 10nf cap +1k resistor+10nf cap ,

Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TIC12400
Is TIC12400-Q1 capable to bias and read analog temperature sensors (NTC) on the ADC inputs?
In theory this should be possible but there are questions:
Wetting current is needed…
