The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

Abstract: This paper presents the design of a novel integrated continuous current sensor (CCS) circuit for class-D audio amplifier and current mode controlled DC-DC converter. The proposed current ...

Texas instruments has introduced a precision bi-directional current sense amplifier than can measure voltage drops across shunt resistors over a common-mode range of -5 to 110V, with survival across ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...

The new current sensor ICs provide enhanced isolation while offering a 40% smaller footprint than existing products, enabling outstanding power density. Allegro MicroSystems, Inc. (“Allegro”) has ...

ROHM’s ultra-compact CMOS op amp – TLR1901GXZ – achieves the industry’s lowest operating circuit current. This IC is optimised to be applied as a measurement sensing amplifier in size-constrained ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...
