M63016FP spindle motor and 4ch actuator drive ic mitsubishi semiconductors mitsubishi electric corporation rev.011126 20 [ the notes on designing the layout of the board] this ic has direct pwm controls for the spindle channel and the slide channel drive, therefore the circuits of the ic are influenced more easily by the pwm switching noise than those have linear controls. please refer to the following notes on the occasion of designing the layout pattern of the board on which the ic is mounted. note1 i t is necessary for some application in order to reduce the pwm noise that pass condensers are connected between power supply pins(vm23:4pin, vm1:22pin, 5vcc:39pin) and gnd pin, even if the power supplies of the application already have pass condensers. the closer the connection points of the condensers are to the pins, the more effective it is to reduce the noise. please refer to the values of the condensers on the page of [an example of the values of the external parts.] (the value of the condensers is only a reference value. it differs in each application because the bad influence of pwm noise relates to the layout pattern of the board.) note2 the feedback point of the spindle channel [the slide channel] is the connected point to the vm1(22pin) [the vm23(4pin)] line from the rsp(15pin) [rsl(8pin)] pin through the sensing resistor rsp[rsl]. therefore the closer the feedback point is to the power supply pin, the more stable the circuits are for the pwm noise. cf. [application circuit] note 3 the farther the large current output lines(especially pwm output lines of the spindle ch. and the slide ch.) which are indicated as wide lines in the fig. [application circuit] are to the small signal input lines, the less the bad influence of the pwm noise comes to be without the cross-talk between a large current output line and a small input signal line. 17
M63016FP spindle motor and 4ch actuator drive ic mitsubishi semiconductors mitsubishi electric corporation rev.011126 20 [ the notes on designing the layout of the board] note5 the closer the gnd side of the capacitor connected with osc pin (30 pin) is to the gnd pin(33pin), which is the nearest gnd to the gnd of the small signal circuit inside the ic, the less the bad influence of the pwm noise on the gnd line comes to be. cf. [application circuit] note4 in case the pwm switching noise influences the ref input, it is necessary for some application that a condenser is connected between ref pin(25pin) and gnd pin. the closer the connection points of the condensers are to the pins, the more effective it is to reduce the noise.
