Datasheet
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
Key Specifications
 PRE Part Power Supply Range: 4.5V to 14V
 DC Motor System Power Supply Range:
4.5V to VPREVCC V
 Actuator System Power Supply Range:
4.5V to VPREVCC V
 Operating Temperature Range: -40°C to +85°C
