For most applications, current measurements are made by sensing the voltage drop across a resistor. There are two locations in a circuit that resistors are commonly placed for current measurements. The first location is between the power supply and ...

One of our products uses a standard 1/10-W surface-mount resistor with a high-side current monitor to detect small load changes at the product’s output. Since this circuit is part of the device’s output, it’s vulnerable to field ...

TI Application Report Introduction For several years Quad-flat no-leads (QFN) package with thermal pad have been standard starting point for high current designs. Technology and trends pushed buck converters to get even smaller and more efficient. ...

For redundancy purposes, a number of power supplies, using ORing diodes, can work into the same load. During maintenance, when you can remove any power supply, the minimum possible power perturbation at the load is desirable. To compensate for the ...

Switching Battery Inc., has unveiled an innovative electronic method for the connection of batteries called para-series. The patent-pending para-series method is based on dynamically switching a group of batteries between series and parallel ...

Figure 1 shows a polarization circuit applicable to ISFET (ion-sensitive field-effect-transistor) sensors. ISFETs are solid-state chemical sensors that measure the pH value of a solution in biomedical and environmental applications, for example. ...

It is not often you get to write a title like the one above. The main methods of generating electricity have been know for years, decades or even centuries. Over that time they have been refined, redesigned, rebuilt with better materials and more ...

ISFETs and MEMFETs (ion-sensitive and membrane FETs) are solid-state chemical sensors that provide an electrical signal associated with the change of a chemical concentration in a solution. These types of sensors need a stable operating point. A ...

Part 1 Three-level (3L) buck off-chip components and their losses Off-chip losses include those across the equivalent series resistance (ESR) in the input, output and flying capacitors, as well as the inductor. Choosing ceramic capacitors with very ...

Introduction Modern portable electronic devices require a high-capacity Lithium-ion battery to power popular features such as high-definition cameras, edge-to-edge high-resolution touchscreens and high-speed data connections. As a result, charging ...
