(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2) It is not allowed to apply an external voltage directly to VREF, COMP, SS, RT, LO, HO pins.

(3) Operating lifetime is de-rated when the pin voltage is greater than 5.5V.

(4) Maximum VREF pin sourcing current is 50uA.

(5) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
