1 / 21 page 1/21 TDA7563PD April 2004 This is preliminary information on a new product foreseen to be developed. Details are subject to change without notice. 1 FEATURES ■ MULTIPOWER BCD TECHNOLOGY ■ MOSFET OUTPUT POWER STAGE ■ DMOS POWER OUTPUT ■ NON-SWITCHING HI-EFFICIENCY ■ HIGH OUTPUT POWER CAPABILITY 4x28W/ 4 Ω @ 14.4V, 1KHZ, 10% THD, 4x40W EIAJ ■ MAX. OUTPUT POWER 4x72W/2 Ω ■ FULL I2C BUS DRIVING: –ST-BY – INDEPENDENT FRONT/REAR SOFT PLAY/ MUTE – SELECTABLE GAIN 30dB – 16dB (FOR LOW NOISE LINE OUTPUT FUNCTION) – HIGH EFFICIENCY ENABLE/DISABLE –I2C BUS DIGITAL DIAGNOSTICS ■ FULL FAULT PROTECTION ■ DC OFFSET DETECTION ■ FOUR INDEPENDENT SHORT CIRCUIT PROTECTION ■ CLIPPING DETECTOR PIN WITH SELECTABLE THRESHOLD (2%/10%) ■ ST-BY/MUTE PIN ■ LINEAR THERMAL SHUTDOWN ■ ESD PROTECTION 2 DESCRIPTION The TDA7563PD is a new BCD technology Quad Bridge type of car radio amplifier in PowerSO36 package specially intended for car radio applica- tions. Thanks to the DMOS output stage the TDA7563PD has a very low distortion allowing a clear powerful sound. Among the features, its su- perior efficiency performance coming from the in- ternal exclusive structure, makes it the most suitable device to simplify the thermal manage- ment in high power sets.The dissipated output power under average listening condition is in fact reduced up to 50% when compared to the level provided by conventional class AB solutions. This device is equipped with a full diagnostics array that communicates the status of each speaker through the I2C bus.
