These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is intended to be functional, but does not ensure specific performance limits. For specifications and test

conditions see the Electrical Characteristics Table.

(2)

See Application Information when input supply voltage is less than the VCC voltage.

(3)

These pins are output pins. As such they are not specified to have an external voltage applied.

(4)

The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin.

Operating Ratings

(1)

4.5V to 42V

VCC

4.5V to 14V

HB to SW

4.5V to 14V

Junction Temperature

-40°C to +125°C

(1)

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is intended to be functional, but does not ensure specific performance limits. For specifications and test

conditions see the Electrical Characteristics Table.

(2)

Minimum VIN operating voltage is defined with VCC supplied by the internal HV startup regulator and no external load on VCC.
