Simplifying lithium-ion (Li+) battery charger testing

Because the charging process for Li+ batteries can take an hour or longer, testing a Li+ battery charger using its natural load (i.e., a battery) is time consuming and inconvenient. This application note presents a simple circuit for simulating the behavior of a Li+ battery, thus providing a more convenient method for testing Li+ battery chargers than using real batteries.

Modern PRTD temperature sensors and high-resolution delta-sigma ADC enable high-precision temperature measurement over a wide range

Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature range with accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinum resistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracy and repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and cost effectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

Obstacle measuring car

A car with intelligent judgment function is designed and produced. The car has the following functions: automatic obstacle avoidance function; tracking function (driving according to the black track on the road); phototaxis function (finding the point light source in front and driving in place); It has the function of detecting the number of iron pieces placed on the road surface; it calculates and displays the distance traveled and the walking time, and can make sounds and light up. The work can be used as a high-end smart toy, or as a powerful application example for college students to learn embedded control.
