CS+ to CS– –0.3 0.3
I(FLT_I) I(FLT_T) 10 mA
I(CS+) to I(CS–)  , 1msec –100 100
Output Pins PU, PD, G, BST to GND –30 112 V

Operating junction temperature, Tj(2) –40 150 °C
Storage temperature, Tstg –40 150
Stresses beyond those listed under Absolute Maximum Rating may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
