BD8226EFV - 4ch System Motor Driver

Description

BD8226EFV is a 5-input, 4-output BTL driver developed for driving Spindle motor (CH1), Sled/Loading motor (CH2) and the actuator coils (CH3:Tracking coil, CH4:Focus coil).

This IC can be used for CD and DVD applications.

Features

  • 4CH BTL Driver.
  • Has wide dynamic range.
  • Built-in thermal shutdown circuit.
  • Separating Vcc into Pre and Power (Power divides into CH1/2 and CH3/4) can improve efficiency.
  • Switches CH2 input using Control input terminal (CNT).
  • Incorporates mute function using CNT and MUTE terminals.
  • Built-in variable regulator control Key Specifications.
  • Power supply voltage.
  • Operating temperature range.
  • Maximum output amplitude (VPREVCC1=VPOWVCC1,2=8V, RL=8Ω) C.
