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 1.3Ω (typ.)
6) Low power consumption.
7) SSOP-B24 package.

∗1 The current is guaranteed 1.0A is case of the current is turned on/off in a duty-ratio of less than 1/10 with a maximum
on-time of 5msec.
∗2 When a 70mm×70mm, 1.6mm thick glass epoxy substrate having a copper foil content of less than 3% is mounted.
When the circuit if used at Ta of 25°C or more, subtract 8.2mW per degree from the rating.
