Technical content

The AN8780SB employs 4ch. H-bridge system that is suitable for driver or actuator of CD player. Also it employs the surface mounting type package superior in radiation characteristics. n Features

  • Wide output D-range is available regardless of refer- ence voltage on the system
  • 4 ch. BTL Driver built-in. Particularly suitable for driver of actuator or motor of 5 to 20Ω load.
  • 2 ch. independently controllable PC (Power Cut) fea- ture, and 4 ch. simultaneously controllable PC feature built-in.
  • Thermal shut down circuit (with hysteresis) built-in.
  • Control for proper heat of IC by separating the power supplies for signal line and output line.
  • Provided with reset output pin.
  • Shot brake mode. n Application CD player, CD-ROM, for drive of motor AN8780SB (Under development) 4Ch.
