(1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for
which the device operates correctly. Operating Ratings do not imply ensured performance limits.
(2) The LG and HG pin can have -2V to -0.5V applied for a maximum duty cycle of 10% with a maximum period of 1 second. There is no
duty cycle or maximum period limitation for a LG and HG pin voltage range of -0.5V to 21V.
