* : Design target value and no measurement is made. The thermal protection circuit is incorporated to protect the IC from burnout or thermal destruction. Since
it operates outside the IC's guaranteed operating range, the customer's thermal design should be performed so that the thermal protection circuit will not be
activated when the fan is running under normal operating conditions.
