4 x 50 W multifunction quad power amplifier with built in diagnostics feature
Features:
■ Multipower BCD technology
■ MOSFET output power stage
■ DMOS power output
■ New high efficiency (class SB)
■ High output power capability 4 x 28 W / 4 @
14.4 V, 1 kHz, 10 % THD, 4 x 50 W max power
■ Max. output power 4 x 72 W / 2
■ Full I2C bus driving:
– Standby
– Independent front/rear soft play/mute

line output function)
– High efficiency enable/disable
– I2C bus digital diagnostics (including DC
and AC load detection)
■ Full fault protection
■ DC offset detection
■ Four independent short circuit protection
■ Clipping detector pin with selectable threshold
(2 % / 10 %)
■ Standby/mute pin
■ Linear thermal shutdown with multiple thermal
warning
■ ESD protection
Description:
The TDA7563B is a new BCD technology quad bridge type of car radio amplifier in Flexiwatt27 & PowerSO36 packages specially intended for car radio applications. Thanks to the DMOS output stage the TDA7563B has a very low distortion allowing a clear powerful sound. Among the features, its superior efficiency performance coming from the internal exclusive structure, makes it the most suitable device to simplify the thermal management 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.
