ELECTRICAL CHARACTERISTICS

Note that the maximum ambient temperature consistent with these

specifications is determined by specific operating conditions in

conjunction with board layout, the rated package thermal impedance and

other environmental factors.

Note 4: This IC includes over temperature protection that is intended to

protect the device during momentary overload conditions. The maximum

rated junction temperature will be exceeded when this protection is active.

Continuous operation above the specified absolute maximum operating

junction temperature may impair device reliability or permanently damage

the device. The overtemperature protection level is not production tested.

Note 5: Dynamic supply current is higher due to the gate charge being

delivered at the switching frequency. See Applications Information.

Note 6: For application concerned with pin creepage and clearance

distances at high voltages, the MSOP package should be used. See

Applications Information.
