Figure 7.5 Example of Short Circuit protection circuit with 3-shunt resistor
The 3-shunt resistor circuit is more complicated and has more considerations than the 1-shunt resistor
circuit. The 3-shunt circuit is popular since it permits detection of individual phase currents. The circuit is very
cost effective, simple and provides good current sensing performance.
Figure 7.5 shows typical circuit for short-circuit detection using diodes. It should be noted that this
circuit is not adequate for the precise over-current detection due to dispersion and temperature dependency
of V F . Also, there are additional considerations when using this circuit as follows :

The SC sensing signal delay time is increased. The R F1 x C F1 time constant delay (t4) is
added so the total delay time becomes:
T TOTAL = t1 + t2 + t3 + t4
The added diode blocks the IC leakage current (approximately 500nA) from Csc pin. If this
current is applied to the capacitor Csc, the Vcsc will be increased to a somewhat higher
value and causes SPM to stop gating even under normal conditions. In order to compensate
for this corruption of SC current sensing voltage, Rcsc must be placed in parallel with Csc.
The recommended value of Rcsc is approximately 47k ? .
For the short circuit state, the diode drop voltage has to be considered to set the SC
protection reference level. The equation is as illustrated below.
V SEN = Vcsc + V F
