Actuator/Motor Driver for CD-ROM
BH6526FV
Description
BH6526FV is a 2channel PWM driver developed for
driving actuator and motor of CD-ROM. This IC has
achieved lower power consumption of the set by using
power MOS FET in output. Furthermore, using a small
SSOP-B16 package and reducing external parts can
achieve the size reduction.
Features
1) Lower power consumption of sets by adopting PWM system
2) Narrow dead band allows good play ability
3) Few external parts required
4) Small SSOP-B16 package
5) Power supply voltage : 5V
Pre-driver block : Vcc+1.7V~11.5V
