Current sensing devices are often desired in the power supply lines of various circuits, such as battery-powered computers, battery chargers or critical circuits requiring thermal forecasting. Figure ...

The main supply voltage in a notebook computer drops when the wall cube is unplugged, because battery voltage is generally lower than that from a wall cube. Even the voltage of a lithium-ion battery ...

Abstract: A high-voltage replica based current sensor is presented, along with challenges and design techniques which are rarely discussed in literature so far. The performance is evaluated by ...

Abstract: To solve the problem that the load current sensing precision of transistor power switch chip was easily affected by the offset voltage of operational amplifier(op-amp), current sensing mode, ...

The global demand for power supplies is expected to exceed USD 46.5 billion by 2031. This growth is fueled by the ...

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 ...

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 ...

A voltage-to-frequency converter (VFC) can easily measure current flow and convert it to a digital signal understood by the timer/counter input of a microcomputer (µC) or microprocessor. It's a ...

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 ...
