MITSUBISHI <CONTROL / DRIVER IC> M56759FP/AFP 4-CHANNEL ACTUATOR DRIVER DESCRIPTION PIN CONFIGURATION (TOP VIEW) The M56759 is a semiconductor integrated circuit designed for a CD-ROM actuator driver. This device can function 4-channelactuators 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 the Current Control mode. Furthermore, this device includes two mute circuits and TSD function. 1 42 MUTE2 VREF 2 41 MUTE1 VREF0 3 40 SOUT2 IN3- 4 39 SIN2- IN3+ 5 38 IN2+ Vm3 6 37 IN2- OUT3 7 36 OUT2 VM3(-) 8 35 VM2(-) VM3(+) 9 34 VM2(+) FEATURES ● Low saturation voltage (at bootstrap). ● (typical 0.7V at load current 500mA) ● Wide supply voltage range.
