1 / 43 page  This is information on a product in full production. January 2015 DocID025375 Rev 5 1/43 TDA7577BLV 2 x 75 W dual-bridge power amplifier with I2C complete diagnostics and "start-stop" profile (6 V operation) Datasheet - production data Features MOSFET (DMOS) output power stage High-efficiency (class SB) Single-channel 1 Ω driving capability – 84 W undistorted power High output power capability 2 x 28 W / 4 Ω @ 14.4 V, 1 kHz, 10 % THD Max. output power 2 x 75 W / 2 Ω, 1 x 150 W / 1 Ω Full I2C bus driving with 4 addresses Low voltage (6 V) operation (i.e. 'start-stop') Gain 16/26 dB Full digital diagnostic (AC and DC loads) Legacy mode (operation without I2C) Differential inputs Fault detection through integrated diagnostics DC offset detection Two independent short circuit protections Diagnostic on clipping detector with selectable threshold (2 % / 10 %) Clipping detector pin ST-BY and MUTE pins ESD protection Very robust against misconnections Description The TDA7577BLV is a new MOSFET dual bridge amplifier specially intended for car radio applications. Thanks to the DMOS output stage the TDA7577BLV has a very low distortion allowing a clear powerful sound, together with high output power capability. It is a very flexible device capable to support the most demanding specifications in terms of power dissipation and battery transitions: its superior efficiency performance, coming from the internal exclusive structure, can reduce the dissipated output power up to the 50 % (when compared to conventional class AB solutions). Moreover it is compliant to the recent OEM specifications thanks to the capability to work down to 6 V ('start-stop' compatibility). This device is also equipped with a full diagnostic array that communicates the status of each speaker through the I2C bus. TDA7577BLV can also drive 1 Ω loads (with parallel connection of the outputs). It is possible also to exclude the I2C bus interface, controlling the device by means of the usual ST- BY and MUTE pins.
