Combined Darlington + Power MOSFET H-bridge (MEC127E)

This article was taken from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States and also from previous articles in other publications, with minor updates. It shows an H-bridge combining Darlington bipolar and MOSFETs, ideal for controlling DC motors and can be used as a shield.

The circuit shown in Figure 1 combines MOSFETs with bipolar Darlington transistors. This block operates in the same manner as described for the previous block.

Combined Bipolar and MOSFET H-bridge (MEC126E)

This article was taken from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States and also from previous articles in other publications, with minor updates. It shows an H-bridge combining bipolar and MOSFETs, ideal for controlling DC motors and can be used as a shield.

The configuration shown by Figure 1 combines bipolar transistors with power MOSFETs. R1 and R2 form a feedback network that determines which bipolar transistor conducts when the power MOSFETs are triggered on.

H-bridge Using Power MOSFETs with Enable (MEC125E)

This article was taken from my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States and also from previous articles in other publications, with minor updates. It shows an H-bridge with external Enable using Power MOSFETs, ideal for controlling DC motors and can be used as a shield.

Adding a power MOSFET as shown in Figure 1, the H-bridge using power MOSFET (MEC124E) can be enabled by an external logic signal. Q5 controls all the current across the bridge and is on when the input IN3 is low, and off when the input is high. The control logic is given by the following table:
