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.
JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For
JC, the “case temp” location is taken at the package top center.
6. All voltages are to be measured with respect to GND, unless otherwise specified.
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to the Block Diagram on page 4 and the
Typical Application schematics on pages 5 and 6. 8V < VD < 20V, RTC = 10.0kΩ, CT = 470pF, TA = -40°C to +105°C, Typical values are at TA = +25°C.
Boldface limits apply over the operating temperature range, -40°C to +105°C.
