Hi,
I'm a newby in electronic design and i would like to submit to you the following design for a h-bridge:
**broken link removed**
I'm planning to use four IRLZ 44 N-Channel logical level gate Mosfet. Each gate would be directly controlled by a TTL level circuit (not on schematics) providing to the h-bridge the following command: bracke, coast, CV, CCV
I would use either shotky diode like 1N5817 or 1N4001/2. Ground of TTL level and motor power supply would be common.
The intent of this design came because I have not been able to find after deep research on the web a Mosfet schematics that would fit my needs: control a 5 to 20V motor consumming maximum 10 A controlled by a PWM at 1 kHz in a very effcient way (ie without transistor). Until now the only schematics I could find was for motor supply above 12V, and in order to keep the design as simple as possible I would like to avoid mosfet driver
My request is therefore: is this design a smoky one, are there some pitfalls I should expect, and by the way is there a simple way to avoid shoot trough?
Thanks in advance for all your remarks and improvments
Olivier
