BD8226EFV
General 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)
