TSC1031 application information doc id 16875 rev 2 19/26 7 application information the TSC1031 can be used to measure current and to feed back the information to a microcontroller. figure 22. typical application the current from the supply flows to the load through the r sense resistor causing a voltage drop equal to v sense across r sense . the amplifier?s input currents are negligible, therefore its inverting input voltage is equal to v m . the amplifier's open-loop gain forces its non-inverting input to the same voltage as the inverting input. as a consequence, the amplifier adjusts current flowing through rg1 so that the voltage drop across rg1 exactly matches v sense . therefore, the drop across r g1 is: v rg1 =v sense =r sense .i load if i rg1 is the current flowing through r g1 , then i rg1 is given by the formula: i rg1 =v sense /r g1 the i rg1 current flows is multiplied by a ratio k2 and the resulting current flows into resistor r g3 . therefore, the voltage drop on the r g3 resistor can be calculated as follows. v rg3 =r g3 .k2.i rg1 =(r g3 /r g1 ).k2.v sense =k1.k2.v sense with k1=r g3 /r g1 =10. the voltage across the r g3 resistor is buffered to the out pin by the voltage buffer, featuring a gain equal to 2. therefore v out can be expressed as: v out = 2.k1.k2.v sense = av .v sense with av= 2.k1.k2 or: v out = av .r sense .i load common-mode volt a ge: 2.9 v to 70 v am06157 5 v v s en s e vo u t lo a d ilo a d r s en s e vp vm o u t rg1 5k rg2 c u rrent m u ltiplier s en s e a mplifier vcc+ t s c10 3 1 a1 vcc - k2 2.5 or 5 controller adc vcc gnd s el gpio rg 3 50k x2 rf2 rf1 rf 3 gnd
application information TSC1031 20/26 doc id 16875 rev 2 the current multiplier gain k2 can be set to 2.5 or 5 depending on the voltage applied on the sel pin. since they define the full-scale output range of the application, the r sense resistor and the amplification gain av are important parameters and must therefore be selected carefully. the TSC1031?s dedicated schematic eases the implementation of emi filtering in harsh environments. a simple f ilter is described in figure 22 , where the input filtering is performed by r f1 , r f2 and c f . the values of r f1 and r f2 should be equal so as to balance the contribution on both amplifier inputs. the value of the c f capacitor should be selected so that the cut-off frequency of the first-order low-pass filter provides enough attenuation to the high frequency interferences. to balance the contribution of r f1 and r f2 in the current sense amplifier gain, an output resistor r f3 should be connected between pin a1 and gnd. the value of r f3 should be chosen according to the following formula. k1 = 10 = r g3 /r g1 = r f3 /r f1 = r f3 /r f2 if these precautions having been taken, the TSC1031?s gain is unaffected by the implementation of the input filtering resistors.
