Other Parts Discussed in Thread: TPS63802, TPS3803
Dear all,
I would like to ask a quesiton about this device
Our customer is planning to start with an input voltage of 3.6V with the following circuit diagram (R3 = R4 = 2kΩ).
However, when checking the data sheet, the threshold value at which EN goes high is min1.2V, and the voltage applied to the VINA pin UVLO is max1.8V.
In other words, EN goes high first, but then VINA is at UVLO. Is there any problem in this case?
If there is a problem, it is considered to set R3 = 4kΩ and R4 = 2kΩ as shown in the following circuit. With this circuit,
I think that the input voltage starts up at 3.6V without any abnormality. Please let me know if there are any problems.
Best Regards,
Y.Ottey
