The company provides a wide range of products including two-way radios, mobile computing devices, and network infrastructure equipment. Motorola Solutions focuses on public safety and commercial and industrial communication solutions. Motorola Mobility was later acquired by Google in 2012, and is now a subsidiary of Lenovo. In 2011, Motorola split into two separate companies: Motorola Mobility and Motorola Solutions. Throughout its history, Motorola was known for its innovation in the field of telecommunications, including the development of the world's first commercially available cellular telephone, the DynaTAC, and the world's first two-way pager, the Pageboy. It was headquartered in Schaumburg, Illinois and was one of the largest providers of mobile phones, telecommunication equipment, and semiconductors. was an American multinational telecommunications company that was founded in 1928. We can minimize energy dissipation by making a rapid transition between the off and on states.Amplifier Transistors Amplifier Transistors

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.
