Motor Driver 48-Pin VQFP T/R

BH5510KV are energy-saving, low noise PWM 6ch ICs developed for the spindle motor, the actuator coil, and the stepping motor drive of notebook PCs and DVD camcorders. Power MOSFET is used for the output steps, and the energy-saving of the set is possible. SIPWMX2 is adopted for the spindle motor driver and is ideal for decreasing noise of the set.

• The spindle motor driver achieves a low noise by SIPWMX2 super low noise drive method.
• The spindle motor driver built the gain switch function in, and it enabled the low-speed stability rotation.
• Actuator coil driver (CH1-CH2) does not have a dead zone (BH5510KV has a very small dead zone) with good linearity.
• Actuator coil driver (CH1-CH2) can be optimized by matching the frequency characteristic to the load characteristic with the external R.C. network
• An eject function can be used when the tilt coil load is not used by the set.
• STBY input (pin4) is three state input, and controls the spindle motor driver only
