WebThe inductor current information needs to be sensed to implement current limiting. The most commonly used current sensing schemes include resistor current sensing, inductor … WebAs discussed previously, shunt resistors function as current measurement devices by dropping a precise amount of voltage for every amp of current through them, the voltage drop being measured by a voltmeter. In this sense, a precision shunt resistor “converts” a current value into a proportional voltage value.

WebMar 22, 2024 · Rds_on <10mOhm Gate & Drain leakage current should be 0nA, since they would sophisticate results very heavily in the nA range. Drain-cut-off current should be around 0.1uA -> As there isn't any MOSFET with this characteristics, especially for the Gate leakage current, maybe a Photo-Transistor would help. WebNov 15, 2015 · I am working on a project in which I am supposed to do current measurements for a sensor node. the range of the current varies from 0-30 mA the sensor node has two modes: 1. active mode (maximum value is 30 mA as stated from the datasheets ) 2. sleep mode (maximum value of current during sleep mode is 35 uA )
