hello everyone. I hope all is well.

i am looking around for a H- bridge that is able to handle approx 30 kh PWM and offer 10v at around 900ma for my motor.

My h bridge does not like such a high frequency so really need to upgrade.

thanks for any help : )
 

If the type is "step-motor" you should think about insulated driver stage to avoid noise to microcontroler.
 

hello thank you both.

i managed to order a L6202 POWERDIP18 yesterday. it is for a dc motor 10v 900ma. so hopefully it should work out.

have a great Christmas. : )
 

hello.

I wonder if anyone knows what rated resistor (in watts) would i need for the "R2" 10 ohm in this schematic below for my h -bridge, i fear i may melt one if i get it wrong .

i am using a 10v motor that has a peak amp usage of aprox 900ma.

thanks for any help : )
 

You can use 0.5watts.
