AN7561Z
BTL output power IC for car audio
s Overview
The AN7561Z is an audio power IC developed as a car audio output (35 W x 4-ch). CR to stop oscillation is built in between the output pin and GND so that a space saving of set is possible. Also, it is incorporating a perfect muting circuit which does not make a shock noise so that a shock noise design in the set transitional state can be made easily when used together with its standby function. In addition, it is incorporating various protective circuits to protect the IC from destruction by GND-open earth short-circuiting and power supply surge which are the important subject of power IC, and the IC will largely contribute to a high reliability design of equipment.

s Usage notes
1. Be sure to use the circuit with an external heat-sink and fix the external heat-sink on chassis when using it. 2. Connect the heat radiating fin to GND potential. 3. This IC has built-in protection circuit against short-circuit to VCC , short-circuit to GND and ASO. However avoid short-circuit to VCC , short-circuit to GND and short-circuit of load. 4. The thermal protection circuit operates at Tj = about 150 C but it automatically returns to the normal operation when the temperature decreases. 5. The over voltage protection circuit operates at VCC = about 20 V. 6. Be especially careful to heat radiation design when used at an increased VCC. 7. Connect the beep sound input pin to GND when the beep sound function is not used. 8. Do not lower the beep sound input pin below - 0.3 V. 9. Keep AUX input pin in open state when AUX function is not used. 10. Connect only GND pin (signal source) to the signal GND of the amplifier in previous stage. * There is a possibility of device destruction under the following conditions; 1. If the power supply pin and GND pin are connected in reverse to the power supply. 2. If the power supply pin and GND pin are in open state and the power supply is connected across the output pins. 3. If the output pin is grounded when GND pin is open. 4. If more than three output pins are grounded to the earth at a time with more than 1.3 short-circuiting resistor with which the protection circuit does not operate. 5. If plus and minus output pins are short circuited to the supply line at a time with more than 1 short-circuiting resistor with which the protection circuit does not operate. 6. If the RF pin and the output pin are short circuited and short-circuited to the earth.
