TPS24710/11/12/13 Hot-Swap Controller Circuit Explained
When we talk about hot-swap controllers, it is basically an electronic device or integrated circuit (IC) that allows you to the insert or/and remove circuit boards, modules or parts within an active system without having you to switch off the system. It regulates the surge current whenever a component is installed and protects from short […]
3 Frequency to Voltage Converter Circuits Explained
As the name suggests frequency to voltage converters are devices that convert a varying frequency input into a correspondingly varying output voltage levels. Here we study three easy yet advanced designs using IC 4151, IC VFC32 and IC LM2907. 1) Using IC 4151 This frequency voltage converter circuit using IC 4151 is characterized by its […]
2 Simple Voltage to Frequency Converter Circuits Explained
A voltage to frequency converter circuit converts a proportionately varying input voltage int a proportionately varying output frequency. The first design is using the IC VFC32 which is an advanced voltage to frequency converter device from BURR-BROWN specifically designed to produce an extremely proportional frequency response to the fed input voltage for a given voltage […]
2 Simple School Bell Timer Circuits Explained
In this article I have explained two very useful school bell timer circuits which can be used for ringing school bell automatically for each period as per the set time duration. The first circuit is designed using a handful of IC 4060, and the second circuit concept is configured around the IC 4017. I have […]
2 Simple Earth Leakage Circuit Breaker (ELCB) Explained
The discussed Earth leakage circuit breaker diagrams will monitor the leakage current level of the earthing line of your house electrical sockets and will trip the appliances as soon a fault is detected. Here I have explained 2 designs, first using transistors only and the second using IC LM324. Introduction If anything goes wrong with […]
