STAT to GND..........................................................-0.3V to +14V
GATE to GND ..............................................-0.3V to (V

+ 8.5V)
ON to GND (Note 1) ................................................. -1V to +14V
CSPD to GND.............-0.3V to the lower of (V

ELECTRICAL CHARACTERISTICS
(V
IN
= +2.7V to +13.2V, T
A
= -40°C to +85°C, unless otherwise noted. Typical values are at V
IN
= +5V and T
A
= +25°C.) (Note 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.
Note 1:
ON can be pulled below ground. Limiting the current to 2mA ensures that this pin is never lower than about -0.8V.
Current into Any Other Pin................................................±50mA
Continuous Power Dissipation (T
A
= +70°C)
SO (derate 5.9mW/°C above +70°C)........................... 471mW
Operating Temperature Range ...........................-40°C to +85°C
Storage Temperature Range.............................-65°C to +150°C
Lead Temperature (soldering, 10sec) ............................ +300°C
