Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

Here’s a handy little current source that’s often used to control the current flowing through a load. Find the equation that defines the i-Load current and account for non-ideal sources. The i-Load ...

The ability to turn on loads in a controlled manner is important in applications where the power budget is limited. Hard switching a load can cause the input power rail to droop and result in a fault.

Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...

Here is a simple method for estimating the actual load on an electric motor without special equipment. But first, a word of caution: Some applications (e.g., a large forced draft fan) require more ...

The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure how ...

In various industries and applications, it’s crucial to monitor the current and frequency of devices in real-time. These ...

Diodes Incorporated has announced the introduction of the AP22913, a 2A single-channel, slew-rate-controlled load switch with true reverse current blocking for high-side load-switching applications.
