Datasheet System motor driver for CD/DVD Player 4ch System Motor Driver for Car Audio BD8266EFV-M General Description Key Specifications BD8266EFV-M is BTL driver of 5 inputs and 4 outputs Input voltage range: 4.5V to 10.0V for Car CDs developed for SPINDLE motor (CH1), Operating temperature range -40 to +85 SLED/LOADING motor (CH2) and coil drive for actuator(CH3:TRAKING CH4:FOCUS). PowVCC1=PowVCC2=8V, RL=8 It can drive motor and coil of the CD/DVD drive. Maximum Output Amplitude (CH1) 6.5V(Typ.) Maximum Output Amplitude (CH2) 7.0V(Typ.) Features Maximum Output Amplitude (CH3,CH4) 6.0V(Typ.) Drive at PowVCC=5V and 8V with wide Maximum Output Amplitude . PowVCC1=PowVCC2=5V, RL=8 Switches SLED/LOADING input by CNT terminal. Maximum Output Amplitude (CH1) 4.1V(Typ.) Incorporates mute function by CNT terminal and Maximum Output Amplitude (CH2) 4.5V(Typ.) MUTE terminal. Maximum Output Amplitude (CH3,CH4) 3.8V(Typ.) Preventing the overcurrent to the load by the FOCUS Over Current Protection (OCP) function. Built-in TSD, UVLO. Package W(Typ.) D(Typ.) H(Max.) PowVCC1 and PowVCC2 are independent, HTSSOP-B24 7.80mm x 7.60mm x 1.00mm and an efficient drive is possible. PowVCC1 : for SPINDLE&SLED/LOADING. PowVCC2 : for TRAKING & FOCUS.
