Thermal Hysteresis
Note 1: Operating characteristics are over Standard Operating Conditions unless otherwise specified.
Note 2: The disturbance on V
CC
during supply changeover should be kept below the hysteresis voltage to prevent any chatter. The
source resistance on the V
CC
supply should be kept to less than 0.3 ohms to ensure precise switching.
