1) Depending on the maximum application output power, external heatsink may be needed.

External heatsink should be fixed to the chassis.

2) Fin of the IC can be connected to GND.

3) Please prevent output to VCC short and output to GND short.

4) The temperature protection circuit will operate at Tj around 150 °C. However, if the temperature decreases, the

protection circuit would automatically be deactivated and resume normal operation.
