Recommended Operating Conditions
Ambient Operating Temperature . . . . . . . . . . . . . . .-40°C to +105°C
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. Θ_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 Θ_JC, the “case temp” location is taken at the package top center.
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.
Electrical Specifications
V_DD = 5V, V_BOOST = 11V, I_LOAD = 200mA, V_ON = 15V, V_OFF = -5V, V_LOGIC = 2.5V, limits over -40°C to
+105°C temperature range, unless otherwise specified. Boldface limits apply over the operating
temperature range, -40°C to +105°C.
