s Usage Notes
1. Always attach an outside heat sink when using the chip. In addition, the outside heat sink must be fastened onto
a chassis for use.
2. Connect the cooling fin to GND potential.
3. Avoid short circuit to VCC and short circuit to GND, and load short-circuit.
4. The temperature protection circuit will be actuated at Tj = approx. 150°C.
However, it is automatically reset when the chip temperature drops below the above set level.
5. The overvoltage protection circuit starts its operation at VCC = approx. 26 V.
6. For the standby voltage, a stabilized power supply of 3 V or higher should be used.
7. Only when being used in combination with the AN7077Z, this IC can operate up to the supply voltage of approx.
25.4 V which is the maximum output voltage of the AN7077Z.
