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 1.5 kΩ resistor into each pin. 2 kV for all pins except HB, HO & HS which are rated
at 1000V.
Note 3: 2 layer board with 2 oz Cu using JEDEC JESD51 thermal board.
Note 4: Min and Max limits are 100% production tested at 25ºC. 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: In the application the HS nodes are clamped by the body diode of the external lower N-MOSFET, therefore the HS node 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,
the HS voltage must never be more negative than VCC-15V. For example if VCC = 10V, the negative transients at HS must not exceed –5V.
