TDA1566 I2C-bus controlled dual channel 46 W/2 , single channel 92 W/1 amplier with load diagnostic features Rev. 02 — 20 August 2007 Product data sheet 1. General description The TDA1566 is a car audio power amplier with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package. The TDA1566 can be controlled with or without I2C-bus. With I2C-bus control gain settings per channel and diagnostic trigger levels can be selected. Failure conditions as well as load identication can be read with I2C-bus. The load identication detects whether the outputs of a BTL channel are connected with a DC or AC load and discriminates between a speaker load, a line driver load and an open (unconnected) load. The TDA1566 can be congured in a single BTL mode and drive a 1 load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel. 2. Features I Operates in I2C-bus mode and non-I2C-bus mode I TH version: four I2C-bus addresses controlled by two pins; J version: two I2C-bus addresses controlled by one pin I Two 4 or 2 capable BTL channels or one 1 capable BTL channel I Low offset I Pop free off/standby/mute/operating mode transitions I Speaker fault detection I Selectable gain (26 dB and 16 dB) I In I2C-bus mode: N DC load detection: open, short and speaker or line driver present N AC load (tweeter) detection N Programmable trig……
