I would like to confirm the DC current detection of TPIC84125-Q1.
The customer did the test for the short to GND and to battery.
In this case, when they shorted to GND, DC current detection operated, but to battery, it did not operate.
The current was about 500mA. I think the cause is their condition. They use VS = 12V.
So, I have questions.
1. Does the specification of IDC (threshould in Low side or or High Side transistor) change by VS value?
2. How does DC current detection operate (check the current or temperature)?
3. If the cause of the problem is low VS voltage, are there any solutions for operating the detection with low VS?
Best regards,
