4ch System Motor Driver IC
BD8229EFV
General Description BD8229EFV is a 5-input, 4-output, BTL driver developed for driving Spindle motor, Sled/Loading motor and actuator coil. The hysteresis comparator for reset is built-in, so the number of parts can be reduced when designing a set.
Features 4CH BTL Driver Wide dynamic range
(VPREVCC=VPOWVCC=8V,RL=8Ω, 6.0V(Typ))
Built-in thermal shut down circuit Separate VCC into Pre and Power (Power divides into
CH1/2 and CH3/4), which can improve power efficiency Switches CH2 input by Control input terminal (CNT) Incorporates mute function by CNT terminal and MUTE
terminal Built in hysteresis comparator for reset
