Precautions on use
1. Thermal breaking protection
2. Overvoltage protection
3. Ground fault protection
4. Load shortcircuit protection
5. Atmospheric fault protection
6. TAB shortcircuit
7. The operation remains normal even when the load is 2 .
8. When the chip temperature abnormally rose, the temperature protection circuit gets actuated, but it is automatically reset
The protective operation starts at the chip temperature of 150˚C 5˚C.
The protective operation starts at V
The protective operation starts when the contact resistance dropped below 0.3 .
The protective operation starts when the contact resistance dropped below 0.3 .
The protective operation starts only when a shortcircuit between pins occurred.
Even TAB short-circuiting with the GND potential causes no breaking trouble.
when the chip temperature dropped below the set level.
