1. general description the tdf8546 is one of a new generation of complementary quad bridge-tied load (btl) audio power amplifiers intended for automotive applications. it has a best efficiency mode with full i 2 c-bus controlled diagnostics, including start-up diagnostics. the tdf8546 can operate at a battery voltage as low as 6 v ma king this amplifier suitable for stop/start-car operation. the new best efficiency principle uses a patented switch technique which reduces switching distortion. to reduce power dissipati on, the new best efficiency principle uses the audio information on all four channels instead of only the front or rear signals. dissipation is more than 65 % less than standard btl when used for front and rear correlated audio signals. dissipation is 35 % less than standard btl when used for uncorrelated (delayed) audio signals between front and rear. it is 17 % less for uncorrelated audio signals when the front or rear information is used. the amplifier uses a complementary dmos output stage in a silic on-on-insulator (soi) based bcd process. the dmos output sta ge ensures a high-power output signal with perfect sound quality. the soi-based bcd process ensures a robust amplifier, where latch-up cannot occur, with good separation between the four independent channels, with every component isolated and without substrate currents. 2. features and benefits ? stop/start-car prepared: keeps operating without audible disturbance during engine start at a battery voltage as low as 6 v ? new best efficiency mode with patented low switching distortion ? extreme best efficiency mode (uses info rmation from 4 channels) with 17 % less dissipation for uncorrelated signals comp ared to 2-channel best efficiency mode. ? operates in either legacy (non-i 2 c-bus) or i 2 c-bus modes (3.3 v and 5 v compliant) ? four hardware-programmable i 2 c-bus addresses ? can drive 2 ? and 4 ? loads ? speaker fault detection ? start-up diagnostics with load detection: open, short, pres ent; filtered for door-slam and chatter relays ? ac load (tweeter) detection with low and high current mode ? gain select after start-up without audible disturbance ? independent selectable soft mute of front and rear channels ? programmable gain (26 db and 16 db), independently programmable for the front and rear channels tdf8546 i 2 c-bus controlled 4 ? 45 w best efficiency amplifier rev. 8 ? 27 september 2013 product short data sheet
