(3)

-0.3 to 7V

SS, RAMP, RT to AGND -0.3 to 7V

CS, CSG, PGND, to AGND -0.3 to 0.3V

ESD Rating HBM

(4)

2kV

Storage Temperature -55°C to +150°C

Junction Temperature +150°C

(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur.

(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 1.5kΩ resistor into each pin.

Operating Ratings

(1)

VIN

(2)

4.5V to 42V

VCC 4.5V to 14V

HB to SW 4.5V to 14V

Junction Temperature -40°C to +125°C

(1) 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.
