TDA75613LV 2 4 x 45 W power amplifier with full I C diagnostics, high efficiency, SSR and low voltage operation Datasheet - production data ESD protection Very robust against misconnections Improved SVR suppression during battery transients Capable to operate down to 6 V (e.g. Start-stop) Flexiwatt27 (vertical) SSR (speaker safety routine) Description Features The TDA75613LV is a new quad bridge car radio Multipower BCD technology amplifier, designed in BCD technology, in order to MOSFET output power stage include a wide range of innovative features in a DMOS power output very compact and flexible device. High efficiency (class SB) The TDA75613LV is equipped with the most High output power capability 4x25 W/4 complete diagnostics array that communicates 2 14.4 V, 1 kHz, 10% THD, 4 x 45 W max power the status of each speaker through the I C bus. 2 driving capability (64 W max power) The dissipated output power under average 2 listening condition is significantly reduced when Full I C bus driving: compared to the conventional class AB solutions, Standby thanks to the patented class SB efficiency Independent front/rear soft play/mute concept. TDA75613LV has been designed to be Selectable gain 30 dB /16 dB (for low noise very robust against several kinds of line output function) misconnections. High efficiency enable/disable 2 The TDA75613LV is equipped with the SSR I C bus digital diagnostics (including DC (speaker safety routine), a procedure able to and AC load detection) check the offset at the speakers and automatically Flexible fault detection through integrated shut down the power amplifier in case of diagnostic dangerous DC voltage. DC offset detection It is moreover compliant to the most recent OEM Four independent short circuit protection specifications for low voltage operation (so called Clipping detector pin with selectable threshold start-stop battery profile during engine stop), (2 %/10 %) helping car manufacturers to reduce the overall emissions and thus contributing to environment Standby/mute pin protection.
