Hi
I am trying to implement DC brush motor control by using Atmel microcontroler (providing PWM) and mosfets.
Because microcontroler cant provide enought current for fast and full switching of mosfets, i am going to use mofset-driver to assure fast switchnig of mosfets.
Here is my question:
In H-bridge circuit, two (of four)mosfets have to be switched simultaneously, which could be a problem for DIY circuit, so could the same be achieved by PWM switching only one mosfet WHILE the other mosfet is permanently ON (at least while motor is turning in one direction)?
Are there also comercially available H-bridges supposed to work that way(fast switching only one mosfet)?
