Part Number: TIC12400-Q1
Other Parts Discussed in Thread: TIC12400,
Hi team,
Please check the question below:
Peripheral Circuit:
12V system, the IO pin of TIC12400 is connected in series with a 1kohm resistor to a detection switch, which is then connected to GND. Capacitors of 4.7nF and 10nF are connected between the two ends of the resistor and GND respectively.
Question Description:
How to ensure signal reliability during detection when the switch is in a wet state (assumed resistance: 2kohm to Mohm range) but actually open-circuited? What are the reasonable register parameter settings, and are there any recommended values?
Questions Regarding Register List:
1. Current Source Register (CURRENT_SRC): What are the reasonable values for sink terminals IN4-IN9 and source terminals IN10-IN15? (Options: 2mA, 5mA, 10mA, 15mA)
2. Comparator Threshold Register (THERS_COMP): What is the recommended parameter? (Options: 2V, 2.7V, 3V, 4V)
3. Detection Filter Register (DET_FILTER): What is the recommended parameter? (Options: 0ms, 1ms, 2ms, 4ms)
4. In multi-channel polling mode, does the polling time (configured via POLL_TIME and POLL_ACT_TIME registers) affect signal acquisition?
Regards,
Eileen
