Note 1: These parameters are not production tested but are guaranteed by design, characterization and
correlation with statistical process control.
Note 2: Current sourced by a pin is reported with a negative sign.
Note 3: Refer to the Auxiliary Power Supply section in the Application Information section for details on the VC
requirement to meet the MOSFET Vgs requirement.
