  • 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.

    Key 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
