BH6546KV - One chip driver for slim CD-ROM/RW/ DVD-ROM

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: 0.5Ω (Typ. ) Slide/Focus/Tracking driver output: 1.2Ω (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.
