UNISONIC TECHNOLOGIES CO., LTD TDA7360 Preliminary CMOS IC 20W BRIDGE/STEREO AUDIO AMPLIFIER WITH CLIPPING DETECTOR DESCRIPTION The UTC TDA7360 is a new technology class AB Audio Power Amplifier in the Multiwatt® package. The high power performance of the UTC TDA7360 is obtained without bootstrap capacitors due to the fully complementary PNP/NPN output configuration The audible on/off noise is eliminated by a delayed turn-on mute circuit, and a novel short circuit protection system prevents spurious intervention. The device provides a circuit for the detection of clipping in the output stages. An open collector output is able to drive systems with automatic volume control. FEATURES * Very few external components * Without boucherot cells * Without boostrap capacitors * High output power * Very low STAND-BY current * Fixed gain (20dB stereo) * Programmable turn-on delay * Clipping detector * No switch on/off noise * STAND-BY function ORDERING INFORMATION Ordering Number Lead Free TDA7360L-J11-T Halogen Free TDA7360G-J11-T www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd Package Packing HZIP-11A Tube 1 of 6 QW-R107-072.a TDA7360 CMOS IC MARKIN PIN CONFIGURATION 11 STAND-BY 10 OUT1 9 +VS 8 OUT2 7 SVR 6 P-GND 5 IN2 (+) 4 OUT BRIDGE 3 S-GND 2 CLIP DET 1 IN1 (+) TAB CONNECTED TO PIN 6 PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 PIN NAME IN1 (+) CLIP DET S-GND OUT BRIDGE IN2 (+) P-GND SVR OUT2 +VS OUT1 STAND-BY DESCRIPTION Amp IN1 (+) Clip detector Signal Ground Bridge output Amp IN2 (+) Power Ground Supply voltage rejection Output2 Supply voltage Output1 Stand-by UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R107-072.a TDA7360 CMOS IC BLOCK DIAGRAM STAND-BY IN 1(+) +VS + OUT1 - SVR CLIPPING DETECTOR CLIP DET OUT BRIDGE OUT2 + S-GND IN 2(+) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw P-GND 3 of 6 QW-R107-072.a TDA7360 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Operating Supply Voltage VS 22 V Output Peak Current (non rep. for t=100µs) IO 5 A Output Peak Current (rep. freq. >10Hz) IO 4 A Power Dissipation At TCASE=85°C PTOT 36 W Storage And Junction Temperature TSTG, TJ -40 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
