*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.
