Electrical Characteristics VIN = 24V unless otherwise indicated. Typical and limits appearing in plain type apply
for TA=TJ= +25°C (Note 4). Limits appearing in boldface type apply over full Operating Temperature Range. Datasheet min/max
specification limits are obtained under device test mode and guaranteed by design, test, or statistical analysis.
