Power AMP for the "turnkey" solution for the big car entertainment system
NXP's TDF8546 is one of a new generation of complementary four-channel bridge-tied load (BTL) audio power amplifiers for automotive electronics applications. The device features an optimal efficiency mode with a full I2C bus to control diagnostics, including startup diagnostics. The TDF8546 operates from a supply voltage as low as 6 V, so the amplifier is suitable for starting/stopping car operation. The new best efficiency principle uses a patented switching technology that reduces switching distortion. To reduce power consumption, the new best efficiency principle uses audio information on all four channels instead of just using the pre (post) signal. When used for front and rear related audio signals, the power consumption is less than 65% less than the standard BTL. For audio signals that are uncorrelated (delayed) before and after, the power consumption is less than 35% less than the standard BTL; when using the pre- (post) information, it is 17% less for the uncorrelated audio signal. Can be applied to car entertainment systems, car audio and so on.
• Stop/start the car at any time: During engine start-up (when the battery voltage is as low as 6 V) continue to operate without audio interference.
• New best efficiency mode with patented low switching distortion.
• Extremely optimal efficiency mode (using information from 4 channels), the power consumption of uncorrelated signals is reduced by 17% compared to the 2-channel best efficiency mode.
• Can drive 2Ω and 4Ω loads.
• Speaker fault detection.
• Startup diagnostics with load detection: open, short, presence; filtered for closing and vibrating relays.
• AC load (tweeter) detection in high/low current mode.
• Programmable gain (26 dB and 16 dB) for independent programming of front and rear channels.
• Line driver mode supports engine start-up with battery voltages as low as 6 V (16 dB and center tap voltage 0.25 VP).
• Programmable thermal warning.
• Prevents ground failure and open circuit VP (minimum series resistance required).
