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.

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

Ω resistor into each pin. LO, HO and HB are rated at 1kV. 2kV

rating for all pins except VIN which is rated for 1.5kV.

Operating Ratings are conditions under which operation of the device is intended to be functional. Operating Ratings do not imply

specified performance limits. For specified performance limits and associated test conditions, see the Electrical Characteristics tables.

(2)

Note: RAMP, COMP are output pins. As such they are not specified to have an external voltage applied.
