Hello,

Is a power cycle absolutely required in case of OTP or OCP triggering, or is a pulse on Reset pin enough ?

Thank you,

Hi Martin,

In addition to cycling power, you should be able to cycle the SLEEPn pin to reset the device.
The RESET pin is not enough.

Set SLEEPn long enough to allow the V3P3 LDO to approach 0.5V. Please try monitoring the V3P3 voltage when entering sleep and then double the time for additional margin.

Thank you !
This is a big deal, maybe it should be detailed in the datasheet ? :-)

Have a nice day,

Martin
