One chip driver for slim CD-ROM/RW, DVD-ROM
BH6546KV
Description
BH6546KV is a 4-channel PWM driver that drives
spindle/slide motor, and focus/track actuator coil
of optical disc. In high speed and 180˚ PWM
driving slim disc, the spindle driver can achieve
low vibration/low noise.
Features
1) Low vibration/low noise by 180˚ PWM driving
2) Charge-pump circuit is not necessary for output
due to complement power MOSFET.
3) Low power consumption due to low ON resistance
Spindle driver output: 0.5(Typ.)
Slide/Focus/Tracking driver output: 1.2(Typ.)
4) 1 phase/3 phase FG output can be switched
by FG switching pin.
5) VQFP48C contributes to make the set smaller and thinner.
