Similarly in the amplification application, it can be connected in three configurations such as common emitter, common collector and common base. A current limiting resistor is also in the circuit for limiting the base current because it could be damaged the transistor if the source current is greater than 5mA.Similarly in the cut-off region, no current flows from emitter to collector then it acts as a turn off the switch.Therefore the user cannot connect the load whose current is greater than 800mA In saturation region full current flows from emitter to a collector that’s range is 110 to 800mA and in this condition, it acts as a turn on a switch.In switching application it works in two regions such as saturation and cut off region Therefore, it could be used in that application such as switching and amplifications where BC547 transistor has been using.But the only difference between them is the continuous collector current and total power dissipation of this transistor.

This 2N2222 NPN transistor has almost the same technical specifications as BC547 NPN transistor.We can minimize energy dissipation by making a rapid transition between the off and on states. This causes heating problems and reduces efficiency. 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.
