As shown in Fig. 2, the detection current calculation method in the present invention：
Sense current ILOADRS- is flowed to from RS+ through accurate sensing resistor Rsense, output end OUT passes through output resistance
ROUT is grounded (GND).At this point, Q2 is disconnected, amplifier A1 work, output current Iout is flowed out from the emitter of Q1.Due to not having
Electric current flows through RG2, and the current potential of the reverse input end of A1 is equal to the current potential of Rsense and RG2 intersection points；Because A1 open-loop gain very
Greatly, positive input is kept substantially same current potential with reverse input end.So the current potential of the positive input of A1 is also approximate
Equal to the current potential of Rsense and RG2 intersection points.Therefore, sense current ILOADIt flows through pressure drop caused by Rsense and is equal to output electricity
Stream Iout flows through pressure drop caused by RG1, i.e.,
IOUT* RG1=ILOAD*Rsense
IOUT=(ILOAD*Rsense)/RG1
Vout=(ILOAD*Rsense*Rout)/RG1
Similarly, if sense current ILOADRS+ is flowed to from RS- through sensing resistor Rsense, then can be obtained
Vout=(ILOAD*Rsense*Rout)/RG2
In summary two kinds of situations can obtain detection circuit output voltage equation
Vout=(ILOAD*Rsense*Rout)/RG；
Wherein Vout --- desired actual output voltage
ILOAD--- the actual current sensed
Rsense --- accurate sensing resistor
Rout --- output regulating resistor
RG1 --- gain resistor RG1
RG2 --- gain resistor RG2
For circuit, set current gain is：Rsense/RG=500 × 10^6, Vout=500 × 10^6 ×
ILOAD×Rout。
When output resistance Rout is 2k Ω, in sense current ILOADAllow variation range (- 3A≤ILOAD≤ 3A) in, it is defeated
The variation range for going out voltage Vout is：- 3V≤Vout≤3V, i.e. full scale voltage value are 3V.
Specifically the output regulating resistor Rout corresponding to full scale range is：
Rout=(Vout*RG)/(ILOAD*Rsense) for this chip Rsense/RG=100 × 10^6, then Rout=
(Vout/ILOAD)*100*10-6
It is noted that when variation Rout, the upper limit value of circuit output voltage must be ensured no more than VRS+-1.5V.
