(1) These are stress limits. Stress beyond these limits may cause permanent damage to the device. Functional operation of the device at

these or any conditions beyond those indicated under RECOMMENDED OPERATING CONDITIONS is not implied. Exposure to

absolute maximum rated conditions for extended periods of time may affect device reliability.

(2) All voltages are with respect to GND.

(3) All currents are positive into the terminal, negative out of the terminal.

(4) In normal use, terminals GDA and GDB are connected to an external gate driver and are internally limited in output current.
