Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical Characteristics. The guar-
anteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2:
At elevated temperatures, devices must be derated based on package thermal resistance. The device in the surface-mount package must be derated at
θ
JA
= 220C/W (typically), junction-to-ambient.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
Note 4:
The absolute maximum peak and continuous currents specified are not tested. These specifications are dependent on the
θ
JA
, which is 220C/W for the
MSOP-8 package.
Note 5:
Typical numbers are at 25C and represent the most likely parametric norm. Specifications in standard type face are for T
J
= 25C and those with
boldface
type
apply over
full operating temperature ranges.
Note 6:
Limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 7:
There is a variation in accuracy over time due to thermal effects. Please refer to the “PWM Output and Current Accuracy” section for more information.
Note 8:
This parameter is production tested at 1A and guaranteed by design at 2A.
Note 9:
The tolerance of the internal lead frame resistor is corrected internally. The temperature coefficient of this resistor is 2600 ppm/C.
