7.1 Absolute Maximum Ratings(1)

over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
Input voltage(2) PVIN, AVIN, EN, SWP, VPOS –0.3 6 V
VNEG –6.5 0.3 V
SWN –6.5 5.5 V
Junction temperature, TJ –40 150 °C
Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) With respect to GND pin.

7.2 ESD Ratings
