DC Electrical Characteristics

The following specifications apply for V

+ = +5V, V

REF(+) = 5V VREF(−) = GND, and Speed Adjust pin connected to ground

through a 14.0 k

Ω resistor (Mode 1) or an 8.26 kΩ resistor (Mode 2) unless otherwise specified. Boldface limits apply for

A = TJ = TMIN to TMAX; all other limits TA = TJ = +25˚C.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-

tional. These ratings do not guarantee specific performance limits, however. For guaranteed specifications and test conditions, see the Electrical Characteristics. The

guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed

test conditons.

Note 2: All voltages are measured with respect to GND, unless otherwise specified.

Note 3: When the input voltage (VIN) at any pin exceeds the power supply rails (VIN < GND or VIN > V

+) the absolute value of current at that pin should be limited

to 5 mA or less. The 20 mA package input current limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four.

Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA and the ambient temperature, TA. The maximum

allowable power dissipation at any temperature is PD = (TJMAX −TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. In most cases,

the maximum derated power dissipation will be reached only during fault conditions. For these devices, TJMAX for a board-mounted device can be found from the

tables below:
