I have limited the connection to ground with another MOSFET, now I use two input pins simple digital pins to control the h-bridge itself clockwise, counterclockwise and stop and a PWM pin to control the h-bridge connection to ground. North America Canada Mexico. They were very hot. Please enter a message. Do I need to replace the Mosfets with faster ones?

I have limited the connection to ground with another MOSFET, now I use two input pins simple digital pins to control the h-bridge itself clockwise, counterclockwise and stop and a PWM pin to control the h-bridge connection to ground. North America Canada Mexico. They were very hot. Please enter a message. Do I need to replace the Mosfets with faster ones? Thanks for your reply. To control the motor, firstly and before all the problems, I was using a Motor Shield bought from DX.
Thanks a lot for your support! Now it works by turning on and off the entire bridge with PWM. I will try to do something like this: Darasheet to an existing parts list Save to a new parts list. I think that should work. If you are exporting your goods please go to the Israel Website. The product detailed below complies with the specifications published by RS Components. And third, I need urf great expertise to help me find where the problem lies. Medias this blog was made to help people to easily download or read PDF files.
The mosfets I am using are: It features two L microchips on it, but it seems like it cannot handle much current. Fernando Melo can you give me the revised schematic of urf H-bridge, which will solves my PWM problem. The foregoing information relates to product sold on, or after, the date shown below.

As I said, firstly I was running on Arduino Motor Shield, which works perfectly on tests without load, discarding coding problems. I think the problem is buffer, or capacitance, or something like irf It does work by turning the motor on and off, irf and lrf but it does not PWM. I read both of the following posts, which are similar to my itf Second, sorry by my English, it is not my mother language.
It has two channels For two DC motorsone of them got burned literally, it catches on fire after some test run on heavy load. You agree that the Information as provided here by RS may not be error-free, accurate or up-to-date and that it is not advice.
