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:
1. θJA 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.
2. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
3. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
Electrical Specifications Typical Values are tested at USB = VDC = 5V and ambient temperature at +25°C, unless otherwise noted. All
maximum and minimum values are guaranteed under the recommended operating conditions.
