Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is limited by TJMAX (maximum junction temperature), θJ-A (junction-to-
ambient thermal resistance) and TA (ambient temperature). The maximum power dissipation at any temperature is: PDissMAX =(TJMAX TA)/θJ-A up to the value
listed in the Absolute Maximum Ratings.
Note 3: Rating is for the human body model, a 100 pF capacitor discharged through a 1.5k
resistor into each pin.
Note 4: Quiescent current is all current flowing to ground when the voltage at the VREG pin is forced to be above the nominal regulating voltage (VREG).
Note 5: Off current is all of the current flowing to ground including all leakage current that would be drawn from the battery connected to the VREG terminal.
Note 6: When the External pin is being used as the driving source, it is recommended to keep the operating point of VEXT ≤ 1V. If greater than 1V, the internal
circuitry would bias IDRIVE to conduct up to the current limit level continuously causing unnecessary power dissipation in the device.
