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. 9.0 ± 0.2 7.0 ± 0.1 37 48 1 Dimension (Units : mm) 9.0 ± 0.2 7.0 ± 0.1 0.5 ± 0.15 0.08 M 36 25 24 13 Features 1) Low vibration/low noise by .
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. Applications CD-ROM, CD-RW, DVD-ROM Absolute Maximum Ratings (Ta=25˚C) Parameter Power MOS supply voltage Control circuit supply voltage Maximum output current Power dissipation Operating temperature range Stora.
