Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of
the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the
Electrical Characteristics tables.
Note 2:
The human body model is a 100 pF capacitor discharged through a 1.5k
resistor into each pin. Pin 2, Pin 3 and Pin 4 are rated at 500V.
Note 3:
4 layer board with Cu finished thickness 1.5/1.0/1.0/1.5 oz. Maximum die size used. 5x body length of Cu trace on PCB top. 50 x 50mm ground and power
planes embedded in PCB. See Application Note AN-1187.
Note 4:
Min and Max limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical
Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 5:
The
θ
JA
is not a constant for the package and depends on the printed circuit board design and the operating conditions.
Note 6:
In the application the HS node is clamped by the body diode of the external lower N-MOSFET, therefore the HS voltage will generally not exceed -1V.
However in some applications, board resistance and inductance may result in the HS node exceeding this stated voltage transiently.
If negative transients occur on HS, the HS voltage must never be more negative than V
DD
- 15V. For example, if V
DD
= 10V, the negative transients at HS must not
exceed -5V.
