5.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
PIN MIN TYP MAX UNIT
VINP to GNDP(3) –0.3 6 V
EN/FLT to GNDP –0.3 6 V
VCC to GNDS (3) –0.3 6 V
SEL to GNDS (3) –0.3 6 V
Total VCC output power at TA=25°C, POUT_VCC_MAX (2) 1.65 W
Operating junction temperature range, 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, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) See the VCC Load Recommended Operating Area section for maximum rated values across temperature and VINP conditions for different VCC output voltage settings.
(3) Less than 1ms. Extended time at this voltage can affect lifetime reliability.
