6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)(1)
MIN NOM MAX UNIT
Input Pins SOURCE to GND –60 60 V
EN to GND –60 60
External capacitance SOURCE 22 nF
VCAP to SOURCE 0.1 µF
External MOSFET max VGS rating GATE to SOURCE 15 V
TJ Operating junction temperature range(2) –40 150 °C
(1) Recommended Operating Conditions are conditions under which the device is intended to be functional. For specifications and test
conditions, see electrical characteristics
(2) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
