CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
5. All voltages referenced to V_SS unless otherwise specified.
6. The operating voltage from HB to GND is the sum of VDD and the HS voltage. The maximum operating voltage from HB to GND is recommended to
be under 114V.
7. _JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
8. For _JC, the “case temp” location is the center of the exposed metal pad on the package underside.
9. Specified at published junction to ambient thermal resistance for a junction temperature of 150°C. Refer to Note 7 for test condition to establish
junction to ambient thermal resistance.
Electrical Specifications V_DD = V_HB = EN = 12V, V_SS = V_HS = 0V. No Load on LO or HO, Unless Otherwise Specified. Boldface limits
apply across the operating temperature range, -40°C to +125°C.
