NOTE: DOUT, DATA READY and FAULT are digital outputs and should not
be driven from external sources. V2P5, REF, TEMPREG and BASE are
analog outputs and should not be driven from external sources.
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:
6. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
7. For _JC, the “case temp” location is taken at the package top center.
Electrical Specifications V_BAT = 6 to 60V, T_A = -20°C to +85°C, unless otherwise specified. Biasing setup as in
Figure 45 on page 26 or equivalent.
