Design reference data
Note) The characteristic values below are theoretical values for designing and not guaranteed.
There are the possibility of breakdown for the following conditions.
1. Always attach an outside heat sink to use the AN7555NZ. In addition, the outside heat sink must be fastened onto
2. Connect the radiation fin to the GND potential.
3. Prevent short circuit to V
4. The thermal protection circuit gets actuated when T
5. The overvoltage protection circuit starts the protection operation at V
6. Take into consideration the heat radiation design particularly when V
7. When the beep sound function is not used, connect to GND the beep sound input pin.
8. Don't down below
9. When the AUX function is not used, open the AUX input pin.
1. Reverse connection of the power supply pin and the GND pin.
2. Connection of the power supply between output pins at open condition of the power supply pin and the GND pin.
3. Short circuit to GND of output pin when the GND pin is open.
4. Short circuit to GND of above the three output pins at the same time with a shorting resistor which does not
5. Short circuit to GND of above the plus and minus output pins at the same time with a shorting resistor which does
6. Short circuit to ground with shorting the RF pin and the output pin.
