The electric motor driver raises the plant efficiency of the multimedia

The intersection of Interpion and semi-conductive company to engaged in ASIC introduce, can be use for the apparatus of the multimedia by first kind ‘ Such as CD broadcaster, DVD broadcaster and VCD broadcaster) 5 passway electric motor driver IC. This kind of type has integrated two kinds of electric motor drivers IC in fact for the electric motor driver of IP4504, for the lowering production cost and power consumption, strengthen heat dissipation capacity. Employ the engineering manager Young Gyu Lee to say, IP4504 is that the first yuan of industry can drive 5 chips with electric motor of the current feedback circuit live according to this company. He says, the conventional method is to separate 4 passway drivers from that logic loads the driver now. IP4504 adopts 28 feet SSOP to capsulate, includes a double-channel BTL (equilibrium does not have voltage transformer) Driver, it is with current feedback one pieces it is double-channel BTL driver and it is single-channel and positively one pieces /direct current motor driver, reverse control. This kind of structure allows the control motor more closely, to high density DVD broadcaster especially like this. IP4504 is through the control current, but not controlling torque comes through control voltage. Just as Lee said, most CD broadcasters need very high voltage during start, a break in may be unstable. IP4504 can keep the stable electric current, makes the work of the electric motor more steady. Company this claim on condition that use the heat sink, surface temperature of IP4504 than with same function the intersection of competition and the intersection of products and low 10oC still. Loading the driver has a speed control pin, so designers can change opening and speed closed of the hard disk drive by power up. IP4504 was developed for CD broadcaster of Japan originally. But Interpion Company estimates, a lot of multimedia products manufacturers of Asia will be interested in this device. Interpion Semiconductor Company: Fax: ( 82) 32-234 3939,Website:
