Resistor-based current sensing is simple, easy to use, low cost, extremely linear and requires no calibration. The statement that voltage across a resistor is directly proportional to the current ...
When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...
Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...
Sensing of current going to a load is a critical and often mandatory requirement in many designs. While there are many contact and non-contact ways to accomplish this sensing, such as using ...
Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...
Electrification has created a new paradigm in automotive power systems; whether the design is a hybrid electric vehicle (HEV) or fully electric vehicle (EV), there are new design challenges to address ...
Melexis has brought out the latest variant from its IMC-Hall current sensor – the MLX91218 Low Field (LF). The MLX91218-LF is designed for lower current applications (below 100 A). It enables smart ...
