(1) 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.
Electrical Characteristics⁽¹⁾
Specifications in standard typeface are for T_J = 25°C, and those in boldface type apply over the full operating junction
temperature range. No load on LO & HO, VCC = 10V, VDD = 5V, HB-HS = 10V, OVS = 0V unless otherwise indicated.

(1) Min and Max limits are 100% production tested at 25ºC. Limits over the operating temperature range are ensured through correlation
using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).
