4-channel actuator driver m5 6 7 5 9 fp /afp mitsubishi des cri pt i o n the m56759 is a semiconductor integrated circuit designed for a cd-rom actuator driver. this device can function 4-channel- actuators by 1 chip due to include 4 channel btl drivers. three channels of this device, ch1, ch2 and ch3 can be controlled by pwm pulse. two of them, ch1 and ch2 can also act in t h e current control mode. furthermore, this device includes two mute circuits and t s d function. f e at ures l low saturation voltage (at bootstrap). l (typical 0.7v at load current 500ma) l wide supply voltage range. (4.5v to 13.2v) l low cross-over distortion. l two naked operational amplifiers l divided motor power supplies into three parts app l i cat i o n cd-rom b l oc k d ia gr a m pi n c o n f i g urat i o n ( to p v i e w ) outline 42p2r-d 42 39 40 41 1 4 3 2 38 5 37 6 34 9 33 10 32 11 31 12 13 14 30 29 7 8 36 35 15 28 16 27 17 26 18 25 19 20 24 23 21 22 m5 6759f p / a f p out3 vm3 ( - ) vm3 ( + ) gnd in3- vref0 in3+ vm3 vref op1+ op2- vcc2 op2+ in4b- vm2 op1out op1- in4a- vm4 ( - ) vm4 ( + ) sout2 sin2- gnd in2+ vm2 ( - ) vm2 ( + ) out2 in2- vcc1 mute2 mute1 in1- in1+ op2out sin1- vm1 sout1 vm1 ( - ) out1 vm1 ( + ) 24 25 27 28 29 30 31 34 35 36 37 38 39 40 mute1 tsd gnd (4pin) 1ch in1+ + - - + ch3 + - + - - + ch4 + - + - - + ch2 + - + - - + ch1 + - vref vref0 4ch vcc1 mute2 + - + - + - + - + + in1- out1 vm1(+) vm1(-) vm2(-) vm2(+) out2 in2- in2+ sin1- sout1 sin2- sout2 vm1 vcc2 vm3(-) vm3(+) in3+ in3- out3 vm3 vm4(-) vm4(+) in4a- in4b- vm2 4 6 7 8 9 12 13 14 15 16 5 2 3 22 23 17 18 19 20 21 1 41 42 10 11 26 32 33 op1+ op1- op1 out op2+ op2- op2 out 2ch 3ch sleep hi:sleep vcc2 vcc1 vref0 + -- - op1 op2 a2 a4 a4 a3 a3 a3 a3 a3 a1 a1 a1 s1 e1 e2 s2 e3 e4 bias
