First of all, note that the circuit as it stands is only really intended to show how a basic current sensor module can be built and act as a stimulus for further improvement. The design is centered ...

Allegro's ACS37030 50-A current sensor protects wide-bandgap GaN devices by sensing current over the industry’s widest ...

Alarm generator then gets current from the emitter of T2 which is regulated by ZD to 3.1 volt and buffered by C1.Resistor R4 ( 220K) determines the frequency of oscillation and the value 220K is a ...

usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a simple low-value resistor; since the voltage across it is proportional to the ...
