Power driver IC for CD changer
BD7960FM
BD7960FM
BD7960FM is a 6-channel driver (4-channel BTL driver + 2-channel loading driver) for car CD changer. This IC integrates
1-channel operational amplifier for various purposes. The size reduction of the set is achieved by integrating loading driver
and actuator driver 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 (RON=1.0Ω).
3) The circuit is provided with loading driver voltage setting terminals.
4) A general Opamp and Pre Opamp are built in.
5) The circuit has a mute switch.
6) The circuit has a reset terminal.
7) A thermal shutdown circuit is built in.
8) Since HSOP-M36 power package is used, the set requires a reduced space.
