BD8229EFV
No.10011EAT01
●Description
BD8229EFV is BTL driver of 5 input 4 output developed for driving Spindle motor, Sled/Loading motor and the actuator coil.
The hysteresis comparator for reset is built in, and the number of parts can reduce.
●Features
1) 4CH BTL Driver
2) HTSSOP-B24 power package is adopted, the set is miniaturized.
3) Has a wide dynamic range（PreVcc=PowVcc=8V,RL=8Ω, 6.0Ｖ(typ.)）
4) Built-in thermal-shut down circuit
5) Separating Vcc into Pre and Power (Power divides into CH1/2 and CH3/4), can make better Power efficiency
6) Switches CH2 input by Control input terminal (CNT).
7) Incorporates mute function by CNT terminal and mute terminal
8) Built in hysteresis comparator for reset
