Part Number: LMR23625-Q1
I would like to know about UVLO operation. There are two UVLO for this device.
Does this device restart by soft-start when VIN is recovered to over VIN_UVLO?
(In this case, EN is connected to other supply rail to keep high level during VIN UVLO.)
2. VCC UVLO
Does this device restart by soft-start when VCC is recovered to over VCC_UVLO?
(In this case, EN is connected to other supply rail to keep high level during VCC UVLO.)
I think in general the VCC UVLO is overlapping VIN UVLO.
I tried in the lab by tying EN to a different rail (3.3V) and ramping VIN close to 3.6V and the part will soft-start
But be careful, on the datasheet abs max for EN pin is VIN + 0.3V. Therefore when VIN is 0, it is not advisable to put EN to be 3.3V
