technology fs210 applica t ion note the example of t y pical application circuit fig 5 is the e x ample of typical ap plicatio n circ uit. the red, yello w , and bla c k wi res a r e the in put points of the motor system : red, the inp u t of power supply; yello w , the output o f fg; black, the gro und sign al . r c is an extern al pull-up re sista n ce for the use of measuri ng fg sign al. in view o f the desi gn, the value of r c coul d be decid ed by the transi s to r saturatio n voltage (v on ), sink current (i c ), and of f-level voltage (v c ). the formula is: r c = c on c i v v ? [ d1 is the reverse prote c tio n diode. as if the r ed and black wires reversely con nect with the power sou r ce, the current will flo w thro ugh th e gro und via ic and coils l1 and l 2 to power sup p ly . und e r su ch kind of circum stan ce s, the ic and co il s a r e ea sy to be burne d out. therefo r e, d1, the reverse protection diode, is ne cessary for the design. howeve r , d1 will al so cause an extra voltage drop on the supply voltage. c1 i s a capa citor to redu ce the rip p le noise ca u s ed durin g the transi ent of the output sta g e s. the volume of the ripple noise depends on the coil impedance and characteristics. fs210 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 fig 5. application circuit rev0.4 may . 21, 2004 (lf) p 10 /fs210
