technology FS200 rev0.2 dec. 31, 2004 (lf) p 9 / FS200 application note the example of typical application circuit fig 5 is the example of typical application ci rcuit. the red, yellow, and black wires are the input points of the motor system: red, the input of power supply; yellow, the output of fg; black, the ground signal. r c is an external pull-up resistance for the use of measuring fg signal. in view of the design, the value of r c could be decided by the transistor saturation voltage (v on ), sink current (i c ), and off-level voltage (v c ). the formula is: r c = c on c i v v ? for example: v c = +5v for ttl level. i c = 10ma at 0.2v saturation voltage the safety value of r c = 470 [ d1 is the reverse protection diode. as if the red and black wires reversely connect with the power source, the current will flow through the ground via ic and coils l1 and l2 to power supply. under such kind of circumstances, the ic and coils are easy to be burned out. therefore, d1, the reverse protection diode, is necessary for the design. however, d1 will also cause an extra voltage drop on the supply voltage. c1 is a capacitor to reduce the ripple noise ca used during the transient of the output stages. the volume of the ripple noise depends on the coil impedance and characteristics. fig 5 application circuit FS200 l1 d1 c1 b wire r wire no so internal circuit of 2-phase dc motor +vcc vcc gnd +vc y wire rc fg output l2
