Overvoltage warning (for the AEK-POW-LDO01J only)
The TW pin provides the output overvoltage (OV) diagnostic. To distinguish between a thermal warning and an
output overvoltage event, two different signals are generated on the same TW output pin. A thermal warning
event detection sets the TW pin low. An output overvoltage event generates a square wave on the TW pin. The
overvoltage detection has a higher priority than the thermal warning detection. Therefore, if both protections are
triggered, the generated signal is a square wave.
