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:
4. The Phase Voltage is capable of withstanding -7V when the BOOT pin is at GND.
5. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
6. θ_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.
7. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
8. For θ_JC, the “case temp” location is taken at the package top center.
Electrical Specifications Recommended Operating Conditions, Unless Otherwise Noted. Boldface limits apply over the operating
temperature range.
