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.
