Hello,
Please answer following question form customer.
Customer wants to use 1 second period pulse output from TCAL terminal.
He does not need watchdog so he wants to connect DONE terminal to GND.
Please advise if TCAL terminal outputs 1 second period pulse (and pulse width is 15.625ms typ as specified on the datasheet) when DONE is connected to GND.
Datasheet P10 has following explanation but I can’t have confidence of TCAL behavior.
Different Utilizations of the TPL5000
Connecting the DONE pin either to GND or to TCAL pin disables the watchdog feature.
If connected to GND, the TPL5000 only sends a reset pulse when the time delay elapses.
Best Regards.
