BD7961FM Optical disc ICs 1/9 Power driver IC for CD changer BD7961FM BD7961FM is a 6-channel driver IC developed for CD changer. In addition to the 4-channel BTL driver and the 2-channel loading driver, the 3.3V regulator and 5.0V regulator used in the peripheral circuit are also incorporated. The size reduction of the set is achieved by integrating functions that were used in two chips into a single chip. ! !! !Applications CD changer ! !! ! Features 1) This circuit is a 6-channel driver IC consisting of four BTL drivers and two loading drivers. 2) Two wide dynamic range loading drivers of MOS output (R ON=1.0Ω). 3) The circuit is provided with loading driver voltage setting terminals. 4) A 5.0V regulator and a 3.3V regulator are built in. (Each regulator has an external PNP transistor and an ON/OFF switch) 5) The circuit has a mute switch. 6) A thermal shutdown circuit is built in. 7) Since HSOP-M36 power package is used, the set requires a reduced space. ! !! !Absolute maximum ratings (Ta=25°C) ParameterSymbol Limits Unit V CC Pd Topr Tstg −55 to +150 15 2200 ∗ −35 to +85 V mW °C °C Supply voltage Power dissipation Operating temperature range Storage temperature range ∗ Reduced by 17.6mW for each increase in Ta of 1°C over 25°C, on less than 3% (percentage occupied by copper foil), 70mm×70mm, t=1.6mm, glass epoxy mounting. ! !! !Recommended operating conditions (Ta=25°C) ParameterSymbolMax.Typ.Min.Unit V CC1 14.0V CC2 14.08.04.5 8.04.5 V V 14.0VCC38.06.0V ∗ When REG2 (5.0-V regulator) is not used, the supply voltage3 (VCC3) is 4.5 to 14.0V.
