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.
4. Signals on D+, D-, L, R, COM-, COM+, CTRL, VBUS exceeding VDD or GND by specified amount are clamped. Limit current to maximum current
ratings.
5. θJA 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.
6. For θJC, 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: VDD = +3.0V, GND = 0V, VBUSH = 3.8V, VBUSL = 3.2V,
VCTRLH = 1.4V, VCTRLL = 0.5V, (Notes 7, 8), unless otherwise specified.
