Power driver IC for CD changer
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.
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 (RON=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.
