Here we are going to talk deeply about snubber circuits and why we must use them with MOSFET H-bridge circuits. Because if we do not put snubber in H-bridge then that MOSFETs might blow off during switching. Specially when we drive inductive loads like transformer, motor, relay, solenoid, etc. then this thing becomes very serious. […]

Reed Switch Sensor Module Explained with Circuit Diagram
Here we will try to understand this reed switch sensor module which may look small and nothing much, but it is actually very useful thing when we want to detect a magnetic field or just want to know if a magnet is coming closer or going away. This thing is called a reed switch sensor […]
Simple Low Dropout Regulator Circuits Explained
The transistorized low dropout voltage regulator circuit ideas explained in the following article can be used for getting stabilized output voltages right from 3 V and above, such as 5 V, 8 V, 9 V, 12 V, etc with an extremely low dropout of 0.1 V. For example, if you make the proposed 5 V […]
IC LM7912, -12V Negative Voltage Regulator Explained
In this post we are going to learn about one super old but gold IC called LM7912 or simply IC 7912. This one is not positive regulator like 7805 or 7812, but it is negative regulator which means it gives -12V output and not +12V. If you are making op-amp circuits or dual power supply […]
Explained: MAX4466 Electret Microphone Amplifier Module with Adjustable Gain
In this post we will be talking about this MAX4466 microphone amplifier module, right? So this is a tiny little circuit that can amplify weak sound signals from an electret condenser microphone (ECM). That means it is going to take a very small electrical signal from the microphone and then boost it up so we […]
EGS002 Datasheet, Circuit Diagram Explained
The driver board EGS002 was created especially for single-phase sinusoid inverters. It makes use of an IR2110S driver chip and an ASIC EG8010 control chip. Protection against voltage, current, and temperature is included into the driver board. LEDs are used to indicate warnings, and fan control is included. Jumpers enable the setting of dead time, […]
