(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) All voltage values are with respect to network ground terminal.
(3) This thermal data is measured with high-K board (4-layer board).
ELECTRICAL CHARACTERISTICS
Over recommended free-air temperature range and over recommended input voltage range (typical at an ambient
temperature range of 25°C) (unless otherwise noted)

(1) During short circuit condition driver current limit comparator will trip and short is detected and driver goes into STANDBY and short flag
is set high in the status register.
