*3 These are design guarantee values, and are not tested.

The thermal protection circuit is implemented to prevent the IC from being thermally damaged or burned when exposed to an environment exceeding

the guaranteed operating temperature range. Thermal design must be carried out so that the thermal protection circuit will never be activated while the

fan is running in a stable condition.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be

indicated by the Electrical Characteristics if operated under different conditions.
