Tool/software:
Hello,
I am designing reset circuit using the TPS3808E-Q1.
To set the reset time of this reset circuit to approximately 10 seconds, connect a 1.65μF capacitor to the CT pin.
This reset circuit uses a manual reset (MR pin) in addition to the power-on reset / reset via the voltage monitor on the SENSE pin.
When resetting frequently using manual reset, I would like to confirm whether the charge stored in the capacitor on the CT pin needs to be completely discharged in order to ensure a reset time of 10 seconds.
If the charge needs to be completely discharged, please tell me the formula to calculate the discharge time.
I will set the manual reset interval taking this discharge time into account.
Regards, MESH
