s 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. 150˚C, 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 VCC26V.
6. The ground fault protective circuit starts the protective operation at 0.3Ω or less of contact resistance.
7. The load short-circuit protective circuit starts the protective operation at 0.3Ω 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 VCC is set high or when the load is 2Ω.
