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.

ABSOLUTE MAXIMUM RATINGS

(1) (2)

VIN1

-0.3V to +6V

VIN2, VIN3, VINLILO1, VINLILO2, VINB1, VINB2

-0.3V to VIN1+0.3V and <6.0V

Logic and control pins: Voltage to GND

-0.3V to VIN1+0.3V and <6.0V

Continuous Power Dissipation(3)

Internally Limited

Junction Temperature (TJ-MAX)

150°C

Storage Temperature Range

-65 to 150°C

ESD Rating(4)

Human Body Model

2kV

Machine Model

200V

(1)

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 under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltages are with respect to the potential at the GND pin.

(3)

Internal thermal shutdown circuitry protects the device fro permanent damage. Thermal shutdown engages at TJ = 150°C (typ.) and

disengages at TJ = 130°C.

(4)

The human-body model is 100 pF discharged through 1.5 k

Ω. The machine model is a 200 pF capacitor discharged directly into each

pin, MIL-STD-883 3015.7.

2.6V to VIN1

VINLILO1, VINLILO2

1.8V to VIN1

All input-only pins

0V to VIN1

Junction Temperature (TJ)

-40 to 125°C

Ambient Temperature (TA)

(3)

-40 to 85°C

Maximum Power Dissipation (TA = 70°C)

1.3 W

(1)

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 under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltages are with respect to the potential at the GND pin.

(3)

In applications where high power dissipation and/or poor package resistance is present, the maximum ambient temperature may have to

be de-rated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX), The

maximum power dissipation of the device in the application (PD-MAX) and the junction to ambient thermal resistance of the package (θJA)

in the application, as given by the following equation: TA-MAX = TJ-MAX (θJA x PD-MAX). Due to the pulsed nature of testing the part, the

temp in the Electrical Characteristic table is specified as TA = TJ.

In applications where high power dissipation and/or poor package resistance is present, the maximum ambient temperature may have to

be de-rated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX), The

maximum power dissipation of the device in the application (PD-MAX) and the junction to ambient thermal resistance of the package (θJA)

in the application, as given by the following equation: TA-MAX = TJ-MAX (θJA x PD-MAX). Due to the pulsed nature of testing the part, the

temp in the Electrical Characteristic table is specified as TA = TJ.

(2)

Junction-to-ambient thermal resistance is highly application and board layout dependent. In applications where high power dissipation

exists, special care must be given to thermal dissipation issues in board design.
