s Precautions on use
1. Thermal breaking protection
The protective operation starts at the chip temperature of 150˚C±5˚C.
2. Overvoltage protection
The protective operation starts at VCC – 26V.
3. Ground fault protection
The protective operation starts when the contact resistance dropped below 0.3Ω.
4. Load shortcircuit protection
The protective operation starts when the contact resistance dropped below 0.3Ω.
5. Atmospheric fault protection
The protective operation starts only when a shortcircuit between pins occurred.
6. TAB shortcircuit
Even TAB short-circuiting with the GND potential causes no breaking trouble.
7. The operation remains normal even when the load is 2Ω.
8. When the chip temperature abnormally rose, the temperature protection circuit gets actuated, but it is automatically reset
when the chip temperature dropped below the set level.
