Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. During powerup the voltage on FAN_FAULT should not be higher than VCC.
NOTE: This device is ESD sensitive. Use standard ESD precautions when handling.
