In this post I will comprehensively explain how to protect mosfets and prevent mosfet burning in electronic circuits by following some basic guidelines related to correct PCB layout, and careful manual handling of these sensitive devices. Introduction Even after connecting everything correctly you find the mosfets in your circuit becoming HOT and blowing off within […]

Connecting Voltage Regulators 78XX in Parallel for High Current
In this post we investigate how to connect popular voltage regulator ICs such as 7812, 7805 in parallel for acquiring high current output from the ICs. Voltage regulator chips mostly have their maximum current output specs fixed to some predetermined levels. Increasing them to a higher level would normally call for external out board transistors […]
5630 SMD LED Driver/Tube light Circuit
In this post I have explained a simple transformerless SMD 5630 type LED tube light circuit which can be built by anybody for illuminating home interior cheaply. The idea was requested by Mr. Smeet. Technical Specifications I am a very big fan of your website and it has been much helpful to me in my […]
Half-Bridge Mosfet Driver IC IRS2153(1)D Datasheet
In this post I have explained the datasheet, specifications, pinout configurations and a few application circuit for the IC IRS2153 which is a half-bridge IC from Texas Instruments. The unique feature of this half bridge driver is that it does not have to depend on external logic sources for the operations, rather allows configuring its […]
3-Phase Signal Generator Circuit using Opamp
Many a times we find it crucial and handy to possess a true three phase signal for evaluating many different electronic configurations such three phase inverters, three phase motors, converters etc. Since it’s not so easy to incorporate single phase to three phase conversion quickly we find this particular implementation difficult to acquire and enforce. […]
Homemade Inductance Meter Circuit
In this article I have explained a simple yet accurate, wide range inductance meter circuit. The design utilizes only transistors as the main active components and a handful of inexpensive passive components. The proposed Inductance meter circuit can measure inductance or coil values accurately over the given ranges and as a bonus the circuit is […]
