LV8210W Functional Description and Notes on External Components
The LV8210W is a system motor driver IC that can implement, with just a single chip, the motor driver circuits required for CD and MD systems. Since the LV8210W provides not only a spindle driver, but drivers (with an H-bridge structure) for sled, focus, and tracking motors, it can contribute to miniaturization and thinner form factors in end products. Since the spindle and sled drivers adopt a direct PWM sensorless drive technique, they provide high efficiency motor drive with a minimal number of external components. Read the following notes before designing driver circuits using the LV8210W to design a system with fully satisfactory characteristics. 1. Output Drive Circuits and Speed Control Methods The LV8210W adopts a synchronous commutation direct PWM drive method to minimize power loss in the output. Low on-resistance DMOS devices are used as the output transistors. (The upper and lower side output block device on-resistance is 0.5 (typical).) The LV8210W spindle drivers control system takes an analog input and uses a V-type control amplifier. The V-type control amplifier based speed control system (gain : 0.25typical) controls the speed by controlling the voltage of the VCTL pin (pin 18) and the VCREF pin (pin 19). The circuit provides positive torque when VCTL is greater than VCREF, and allows the application to select either reverse torque braking (when the BRK pin is low) or shortcircuit braking (when the BRK pin is high) when VCTL is less than VCREF. The PWM frequency is twice the frequency of the charge pump pulse rate (pin 5).

2. Soft Switching Circuit This IC performs "soft switching", which is a technique that varies the duty and achieves quieter motor operation by reducing the level of motor drive noise. This IC provides a "current application on/off dual sided soft switching" type soft switching function. 3. Current Limiter Circuit The current limit value of the current limiter circuit is determined by RF in the equation I = VRF/Rf (here, VRF = 0.20V, typical). The current limiter circuit detects the RF1 pin (pin 1) peak current at the RF2 pin (pin 2) and turns the sink side transistor off. 4. VCO Circuit Constants The LV8210W spindle block adopts a sensorless drive technique. Sensorless drive is implemented by detecting the back EMF signal generated by the motor and setting the commutation timing accordingly. Thus the timing control uses the VCO signal. We recommend using the following procedure to determine the values of the VCO circuit's external components. 1) Connect components with provisional values. Connect a 2.2F capacitor between the VCOIN pin (pin 16) and ground, connect a 68k resistor between the RMAX pin (pin 14) and ground, and connect a 2200pF capacitor between the VCO pin (pin 15) and ground. 2) Determine the value of the VCO pin (pin 13) capacitor. Select a value such that the startup time to the target speed is the shortest and such that the variations in startup time are minimized. If the value of this capacitor is too large, the variations in the startup time will be excessive, and if too small, the motor may fail to turn. Since the optimal value of the VCO pin constant differs with the motor characteristics and the startup current, the value of this component must be verified again if the motor used or any circuit specifications are changed. 3) Determine the value of the RMAX pin (pin 14) resistor. Select a resistor value such that the VCOIN pin voltage is about VCC - 1.1V or lower with the motor operating at the target maximum speed. If the value of this resistor is too large, the VCOIN pin voltage may rise excessively. 4) Determine the value of the VCOIN pin (pin 16) capacitor. If the FG output (pin 9 and 10) pulse signal becomes unstable at the lowest motor speed that will be used, increase the value of the VCOIN pin capacitor. 5. S/S and MUTE Circuit The S/S pin (pin 30) functions as the spindle motor driver's and the actuators motor driver's start/stop pin ; a high-level input specifies that the operation is in the start state. The MUTE pin (pin 32) operates on all driver blocks other than the spindle block; a low-level input mutes these outputs. In the muted state, the corresponding drivers (H bridge) all go to the high-impedance state, regardless of the states of the logic inputs. A low level input must be applied to the S/S pin to set the IC to the standby state (power saving mode). When power is supplied to VCC, set either S/S pin or MUTE pin (or both) to low-level. 6. BRK Circuit The BRK pin (pin 31) switches between reverse torque and short-circuit braking; a high level selects short-circuit braking and a low level selects reverse torque breaking. When the motor speed becomes adequately slow in the reverse torque braking state, the application must switch to the short-circuit braking state to stop the motor. (Note: The IC must not be in the power saving state at this point.) When stopping the motor in the state where the control voltage, VCTL, is less than VCREF (when a low level is input to the BRK pin), if the timing of the switch to short-circuit braking is too early, and remaining motor rotation is a problem, reduce the value of the RMAX pin (pin 14) resistor. Also, if motor oscillation continues when the motor is nearly stopped, and a switch to short braking mode does not occur, insert a resistor with a value of a few k at the COM pin. (Note: Verify that inserting this resistor does not adversely affect the startup characteristics.) 7. FG Output Circuit The FG3 pin (pin 10) is the spindle block FG output pin. It provides a pulse signal equivalent to that provided by systems that use three Hall-effect sensors. The FG1 pin (pin 9) outputs a signal that follows the spindle output U phase back EMF voltage. The FG1 and the FG3 pins both have a MOS open-drain output circuit structure. This means that external pull-up resistors must be provided. Connect the power supply from the FG signal input side as the pull-up resistor power supply. We recommended using a resistor of about 10k.

8. Spindle Block Position Sensor Comparator Circuit The spindle block position sensor comparator circuit uses the back EMF signal generated by motor rotation to detect the rotor position. The output block power application timing is determined based on the position information acquired by this circuit. Startup problems due to noise on the comparator inputs can be ameliorated by inserting a capacitor (1000 to 4700pF) between the COMIN pin (pin 12) and the FIL pin (pin 11). 9. Charge Pump Circuit Since the LV8210W has a DMOS (n-channel) output structure, it includes a charge pump based voltage step up circuit. When capacitors (recommended value : 0.22F or higher) are connected between the CP and CPC pins, the IC generates a level that is twice the VCC voltage (or 9.5V). It is desirable that this IC be used with the voltage relationship between the stepped-up voltage (VG) and the motor supply voltage (VS) meeting the condition VG - VS 3.5V. Note that the stepped-up voltage (VG) is, by design, clamped at about 9.5V DC. If the stepped-up voltage (VG) exceeds 10V (VG max) due to ripple, the value of the VG pin capacitor must be increased. Observe the following points if the VG voltage is supplied externally. 1) The externally applied VG voltage must not exceed VG max in the Absolute Maximum Ratings. 2) The capacitor between the CP and CPC pins (pins 5 and 6) is not required. 3) The sequence in which the VG voltage is applied requires care. The VG voltage must be applied after VCC, and must be removed before VCC is cut. 4) Since there is an internal diode between the VCC and VG pins in the IC, a voltage such that VCC > VG must never be applied to the VG pin. 10. Actuator Block The LV8210W incorporates three H bridge channels for use as actuator drivers for the sled, focus, and tracking systems. Hduty of OUTR and OUTF will be OUTR < OUTF when the voltage level at the IN pin is greater than VCREF.

11. Notes on PCB Pattern Design The LV8210W is a system driver IC implemented in a Bi-DMOS process; the IC chip includes bipolar circuits, MOS logic circuits, and MOS drive circuits integrated on the same chip. As a result, extreme care is required with respect to the pattern layout when designing application circuits. (1) Ground and VCC/VS wiring layout The LV8210W ground and power supply pins are classified as follows. Small-signal system ground pins SGND (pin 25), TGND (pin 17) Large-signal system ground pins PGND1 (pin 43), PGND2 (pin 40), PGND3 (pin 35) Small-signal system power supply pin VCC (pin 8) Large-signal system power supply pins VS (pin 3), VS1 (pin 44), VS2 (pin 39), VS3 (pin 33) A capacitor must be inserted, as close as possible to the IC, between the small-signal system power supply pin (pin 8) and ground pins (pin 17, 25). The large-signal system ground pins (PGND) must be connected with the shortest possible lines, and furthermore in a manner such that there is no shared impedance with the small-signal system ground lines. Capacitors must also be inserted, as close as possible to the IC, between the large-signal system power supply pins (VS) and the corresponding large-signal system ground pins. (2) Positioning the small-signal system external components The small-signal system external components that are also connected to ground must be connected to the small-signal system ground with lines that are as short as possible.
