904 00000195 BA5952AFP (4-channel BTL driver for CD-ROM drives) (HSOP-28 Package with Fins) BA5952AFP  4-channel BTL driver for CD-ROM drives

The BA5952AFP is a four-channel BTL driver IC for driving the motors and actuators in products such as CD ROM drives.
Two of the channels use current feedback to minimize the current phase shift caused by the influence of load inductance.

* Applications
CD-ROM drives, DVD drives, DVD ROM drives.

* Features
1) Two channels are current-drive-type BTL drivers for two-shaft actuators.
   One channel is a voltage-drivetype BTL driver for transport motors,
   and the last is a current-drive-type BTL driver for loading motors.
2) Wide dynamic range (4.0V (typ.) when PreVCC = 12V, PVCC = 5V, and RL = 8W).
3) Level shift circuit on chip.
4) Thermal shutdown circuit on chip.

* Dual-shaft actuator drivers
  These drivers use current feedback to minimize the current phase shift cause by the influence of load inductance.
  Output structure is power op-amp to minimize back-rush noise.

* Transport motor driver
  Differential input and signal addition is possible by connecting general-purpose op-amps to the inputs.

* Loading driver
  Performs forward and reverse drive with transistor logic input. Can also be used as a linear BTL driver. 0.89
