BH6573FV
Optical disc ICs
PWM driver for CD
BH6573FV
BH6573FV is a 4-channel PWM driver developed for driving stepping motor, and DC motor of DSC, and also developed
for driving DC motor, and actuator of CD / MD.
This IC has achieved lower power consumption of the set by using power MOSFET in output.
!
Applications
CD, MD, DSC, DVC
!
Features
1) Four channels of power MOS-H bridges are contained.
2) Available for PWM input.
3) Applicable for stepping-motor drive.
4) Separating VM into CH1, CH2 and CH3 / 4.
5) Low on-resistance 1.3鈩?(typ.)
6) Low power consumption.
7) SSOP-B24 package.
