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.
