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. Signals on LIN, RIN, COM-, COM+, IN and CTRL exceeding VDD or GND by specified amount are clamped. Limit current to
maximum current ratings.
7. 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.
8. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications - 2.7V to 3.6V Supply Test Conditions: V_DD = +3.0V, GND = 0V, V_CTRL = 1.4V, V_IN = 0.5V,
(Notes 9, 10), Unless Otherwise Specified. Boldface limits apply over
the operating temperature range, -40°C to +85°C.
