Precautions on use
1. Always attach an outside heat sink to use the chip. In addition, the outside heat sink must be fastened onto a chassis for use.
2. Connect the radiation fin to the GND potential.
3. Prevent atmospheric and ground faults, and load short-circuit.
4. The temperature protective circuit gets actuated when Tj = approx. 150C, but it is automatically reset when the chip
temperature drops below the above set level.
5. The overvoltage protective circuit starts the protective operation at V
CC
26V.
6. The ground fault protective circuit starts the protective operation at 0.3
or less of contact resistance.
7. The load short-circuit protective circuit starts the protective operation at 0.3
or less of contact resistance.
8. The atmospheric fault protective circuit protects the chip only from short-circuit between pins.
9. Take into consideration the heat radiation design particularly when V
CC
is set high or when the load is 2
