AN8780SB (Under development)
4Ch. Linear Driver IC for CD/CD-ROM
s Overview
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.
s 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.
s Application
CD player, CD-ROM, for drive of motor
