It is incorporating various protective circuits to protect the IC from destruction by GND-open, short circuit to GND and power supply surge which are the important subject of power IC protection, so the IC will largely contribute to a high reliability design of equipment. Also, it is incorporating a perfect muting circuit which is free from shock noise, so that a shock noise design under the set transient condition can be made easily using together with its standby function. 29.75±0.3 28.0±0.3 20.0±0.3 (10.0) (10.0) ■ Overview 15 1.27 0.50+0.20 –0.10 (0.61) (1.80) (2.54) R0.55 (1.95) 0.25+0.15 –0.05 19.00±0.30 19.30±0.30 HZIP015-P-0745A ■ Applications • Car audio 1 AN7190NK, AN7190NZ ICs for Audio Common Use 1 12 VCC ■ Block Diagram 3 Ch.1 GND 14 Ref. 4 Ch.1 out (−) 13 Protection cct.

Note that, 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, but 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. 20 V. 6. Take into consideration the heat radiation design particularly when VCC is set high or when the load is 2 Ω. 7. When the beep sound function is not used, open the beep sound input pin (pin 10) or connect it to pin 9 with around 0.01 µF capacitor. 8. Connect only pin 9 (ground, signal source) to the signal GND of the amplifier in the previous stage. The characteristics such as distortion, etc. will improve. ■ Technical Information • PD Ta curves of packages • HZIP016-P-0665A (AN7190NK) PD T a 65 62.5 60 Infinite heat sink • HZIP015-P-0745A (AN7190NZ) PD T a 120 Rth (j−c) = 2°C/W Rth (j−a) = 42°C/W 55 Rth (j−c) = 1.1°C/W Rth (j−a) = 68.3°C/W Infinite heat sink 113.6 100 45 Power dissipation PD (W) Power dissipation PD (W) 50 1°C/W heat sink 41.7 40 35 2°C/W heat sink 31.3 30 3°C/W heat sink 25 20 17.9 5°C/W heat sink 80 60 59.5 1°C/W heat sink 40.3 40 2°C/W heat sink 3°C/W heat sink 30.5 15 10.4 10 10°C/W heat sink 5 3.0 Without heat sink 10°C/W heat sink 11.3 Without heat sink 1.8 0 0 0 25 50 75 100 Ambient temperature Ta (°C) 4 5°C/W heat sink 20.5 20 125 150 0 25 50 75 100 Ambient temperature Ta (°C) 125 150 ICs for Audio Common Use AN7190NK, AN7190NZ 15 14 13 0.22 µF 2.2 Ω 2.2 Ω 0.22µF CRF 12 4.7 kΩ 1 µF 10 µF 4.7 kΩ 0V Mute 2/4 Ω VIN (ch.2) 0V STB 5V Beep in 5V VIN (ch.1) 4.7 kΩ 0.22 µF 33 µF 11 10 9 8 7 6 5 4 2.2 Ω 2/4 Ω 2.2 Ω 0.22 µF VCC 3 2 2 200 µF 1 ■ Application Circuit Example Note) Standby state when STB pin is open-circuit.
