H-bridge Gate Drivers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for h-bridge Gate Drivers. Bbk smp129hdt2 obnovlenie proshivki. My bolt 4g.
Our portfolio spans a variety of configurations, voltage classes, isolation levels, protection features, and package options. State-of-the-art discrete switch families of and silicon MOSFETs, IGBTs, Gallium Nitride HEMTs, and Silicon Carbide MOSFETs as well as such as Easy, Econo power modules, require tuning of gate drive circuits to take full advantage of their capacity and capabilities. An optimum gate drive configuration is essential for all power switches, whether they are in discrete form or in a power module. Our EiceDRIVER™ gate drivers provide advanced features such as integrated bootstrap diode(BSD), over current protection, shutdown, fault reporting, enable, input filter, OPAMP, DESAT, programmable deadtime, shoot through protection, active miller clamp, active shutdown, separate sink and source outputs, short circuit clamping, soft shutdown, two level turn off, galvanic isolation(functional, basic and reinforced), etc.

Structure of an H bridge (highlighted in red) H bridges are available as, or can be built from. The term H bridge is derived from the typical graphical representation of such a circuit. An H bridge is built with four switches (solid-state or mechanical). When the switches S1 and S4 (according to the first figure) are closed (and S2 and S3 are open) a positive voltage will be applied across the motor. By opening S1 and S4 switches and closing S2 and S3 switches, this voltage is reversed, allowing reverse operation of the motor. Using the nomenclature above, the switches S1 and S2 should never be closed at the same time, as this would cause a short circuit on the input voltage source.
The same applies to the switches S3 and S4. This condition is known as shoot-through. Operation [ ]. The two basic states of an H bridge The H-bridge arrangement is generally used to reverse the polarity/direction of the motor, but can also be used to 'brake' the motor, where the motor comes to a sudden stop, as the motor's terminals are shorted, or to let the motor 'free run' to a stop, as the motor is effectively disconnected from the circuit. The following table summarises operation, with S1-S4 corresponding to the diagram above.
