ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VS = +9V to +72V, GND = 0V, ON/OFF open circuit, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VS = +48V

and TA = +25°C.) (Notes 1, 2)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Terminal Voltage (with respect to GND unless otherwise noted)

VS, DRAIN, PGOOD, PGOOD ................................-0.3V to +76V

ON/OFF ....................................................................-0.3V to +4V

GATE to VS ............................................................-12V to +0.3V

Current into any Pin ............................................................±3mA

Continuous Power Dissipation (TA = +70°C)

6-Pin SOT23 (derate 9.1mW/°C above +70°C)..........727mW

6-Pin TDFN (derate 18.2mW/°C above +70°C) .......1454mW

Junction to Case

Thermal Resistance, θJC (TDFN) ..............................8.5°C/W

Maximum Junction Temperature .....................................+150°C

Storage Temperature Range .............................-60°C to +150°C
