9.Application and recommended usage of current sensing resistors
9.1 DC power source
・Shown below are current sensing circuit in simple power source and protect rush current circuit
・In these circuits, current sensing resistors are placed in load current supply line. By measuring the voltage of the current sensing resistor using Op-amp or control IC, current is measured.
・Applications:Various DC power supply circuits
・Recommended products: | KRL series(long side terminal), KRL series((short side terminal), KRL series(4 terminal) |
9.2 DC-DC converter
・Such as DC-DC converter below, in order to monitor output, current sensing resistors are placed out side of the converter.
・To minimize the power loss by the resistor, very low resistance resistors are used.
Current sensing Resistor

Torex Semiconductor Co.
DC-DC Convertor
Current sensing circuit example in DC- DC Converter
(Example circuit by Torex Semiconductor XC9104D093 Datasheet)
・Application examples:Various DC-DC converter, POL(Point of Load)
・Recommended products: | KRL series(long side terminal), KRL series(short side terminal), KRL series(4 terminal) |
9.3 Motor driving circuits
・There are 2 purposes to use current sensors in motor driving circuits such as below. To protect the circuit and to detect the phase of motor driving voltage.
・In order to save space, very low resistance shunt resistors are used for phase detection circuits.
・Application examples:Motor driving circuits, Inverter circuits
・Recommended products: | KRL series(long side terminal), KRL series(short side terminal), KRL series(4 terminal) |
