Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 4. JA is measured in free air with the component mounted on a high-effective thermal conductivity test board with “direct attach” features. See TB379 5. For JC, the “case temp” location is taken at the package top center. Electrical Specifications VIN =VIN_IO = EN = 3.7V, TA = +25°C unless otherwise noted. Boldface limits apply over the operating temperature range, -40°C to +85°C.
