zApplications
CD-ROM slim, DVD-ROM slim set
zFeatures
1) OP amp. is incorporated for input of each driver
to construct filter easily.
2) Built-in low ON resistance power MOS.
3) Built-in current limit, hall bias, FG output and inversion protection
for 3-phase PWM driver.
4) Built-in standby circuit.
5) Built-in thermal shutdown circuit.
6) High-efficient CD drive system achieved by using this IC and 2ch
PWM driver BH6526FV in pairs.
