2

The thermal shutdown temperature shown in this table does not assure the above thermal shutdown operating temperature range of the device operation. The
operating assurance range of the device covers up to Tjmax defined with the absolute maximum rating. The thermal shutdown operation shown in this table is a
thermal protection circuit applied when the temperature exceeds this Tjmax by mistake. Therefore, be sure to operate this device at the temperature lower than
or equal to Tj=150˚C.
