Dear All,
About Absolute maximum rating of TLV 62090.
The PG voltage range is 0.3 to Vin + 0.3 V.
However, PG is an open drain output.
Why is the maximum value not an absolute value?

Hello Kurokawa-san,
There is an ESD protection diode tied between the PG and VIN pins of the device. Having a PG voltage higher than VIN by 0.3V can turn-on the diode and potentially damage the device.
