IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: T J = T C = T A
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. 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.
2. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
3. PSI JT is the PSI junction-to-top thermal characterization parameter. If the package top temperature can be measured with this rating then the
die junction temperature can be estimated more accurately than the θ JC and θ JC thermal resistance ratings.
4. Limits established by characterization and are not production tested.
Electrical Specifications
All specifications below are tested at T A = -40°C to +85°C; V IN = 12V, EN = 5V, R SET = 36.6k Ω ,
unless otherwise noted. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise
specified. Temperature limits established by characterization and are not production tested.
