TDA75610SLV 4 x 45 W power amplifier with full I2C diagnostics, high efficiency and low voltage operation Datasheet - production data  Improved SVR suppression during battery transients  Capable to operate down to 6 V (e.g. “Start-stop”) Flexiwatt27 (Horiz.) Description The TDA75610SLV is a new quad bridge car radio amplifier, designed in BCD technology, in order to include a wide range of innovative features in a very compact and flexible device. The TDA75610SLV is equipped with the most complete diagnostics array that communicates the status of each speaker through the I2C bus.  Multipower BCD technology  MOSFET output power stage  DMOS power output  High efficiency (class SB)  High output power capability 4x25 W/4 Ω @ 14.4 V, 1 kHz, 10% THD, 4 x 45 W max power  2 Ω driving capability (64 W max power)  Full I2C bus driving: – Standby – Independent front/rear soft play/mute – Selectable gain 26 dB /16 dB (for low noise line output function) – High efficiency enable/disable – I2C bus digital diagnostics (including DC and AC load detection)  Flexible fault detection through integrated diagnostic  DC offset detection  Four independent short circuit protection  Clipping detector pin with selectable threshold (2 %/10 %) The dissipated output power under average listening condition is significantly reduced when compared to the conventional class AB solutions, thanks to the patented 'class SB' efficiency concept. TDA75610SLV has been designed to be very robust against several kinds of misconnections. It is moreover compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' battery profile during engine stop), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection. The ST BCD in combination with 'class SB' efficiency and 'intelligent power' has been sold in million of units to most known car manufacturers, the TDA75610SLV is the latest and most compact member of this power amplifiers family. Table 1. Device summary Order code Tube Tape and reel  Linear thermal shutdown with multiple thermal warning  Very robust against misconnections December 2014 This is information on a product in full production.
