PMW motor driver IC for slim type CD-ROM
BH6530KV / BH6534KV
BH6530KV / BH6534KV is a motor driver IC developed for CD-ROM, and DVD-ROM. This IC integrates 3-phase PMW
driver for driving spindle motor and PMW driver for driving feed motor.
BH6530KV
FG signal 1 phase output
BH6534KV
FG signal 3 phase synthesis output
Applications
External dimensions (Unit : mm)
CD-ROM slim, DVD-ROM slim set
Features
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.
