WebDennis Hudgins, Current Sensing Products Discrete implementations of current sense amplifiers are commonly used for low side current sensing applications. Low-side current sensing is when the voltage is measured across a sense resistor that is placed between the load and ground. Figure 1 shows the configuration for low side current sensing ... WebThe current sense threshold on the LTC3873-5 is 95mV, so a current sense resistor of 63mOhms ensures a peak current of 1.5A. The above calculations have not accounted for the efficiency of the dc/dc converter, so a current sense resistor of approx. 80% of this value is a more realistic figure. the elexco group
