The 2N2222 transistor is also known for its switching capabilities, hence it's widely used in digital circuits. The transistor can be used as a switch or an amplifier depending on the bias applied to the base terminal. The emitter is the negative terminal, the base is the control terminal, and the collector is the positive terminal. The 2N2222 transistor has three regions: the emitter, base, and collector. The 2N2222 is known for its reliability and ease of use. It was one of the first transistors that were widely used, and it is still used today in a wide range of applications. The 2N2222 is a type of bipolar junction transistor (BJT) that is commonly used as a small-signal NPN transistor.

Significant energy dissipates by MOSFET whenever the gate is not fully on or fully off. This shorts the power supply and will likely damage the MOSFETS.

Shoot-through means that the two MOSFETS are on at the same time.

So it must be kept in consideration Shoot through The following things fall under consideration while creating H-Bridge motor driver circuit: Electrical Noiseĭuring the working of the H-Bridge motor driver circuit, the motor can make noises and can damage the MOSFETS. When terminal B is grounded and C is connected to +Vcc, transistors Q3 and Q2 will be on and current passes through the motor from right to right causing the motor to revolve in the opposite direction. When terminal D is grounded and A is connected to +Vcc, transistors Q1 and Q4 will be on and current passes through the motor from left to right. The Working of this circuit is very easy to understand. Thus it protects the corresponding MOSFET from damage. The diodes D1 to D4 provide a safer path for the back EMF from the motor. The MOSFETS are used as switches and are activated in diagonal pairs. In the circuit, we see that the 4 MOSFET surrounding the motor form an “H” shape.
