    hello,i am trying to design 30V mosfet H-bridge, after lots of search i decided to use push-pull as mosfet driver but push-pull needs level shifter to interface with microcontroller.
    so i need 0-5v to 0-10v level shifter for low side mosfets and 0-5v to 20-30v for high side mosfets . any suggestions?

    Your easiest solution would be to use an H-bridge driver IC.

    However, you really should describe your project as well as you can. We might be able to help you avoid a number of pitfalls.

    the only mosfet driver i could found was ir2110 which is supposed to drive mosfets in smps So it is not possible to drive the motor in one way continuously without a PWM control signal (as i understand) and it is quit expensive.
    i couldn't find any H-bridge driver IC any place near by
    my project is a 30V ,6A H-bridge for dc motor using p and n type mosfets ,th circuit is supplied by 30V power supply, i use microcontroller to generate 5KHz PWM (5V) so there should be some kind of level shifter between mcu and the push-pull mosfet driver(complementary emitter follower low power bjt)
    sorry for my bad english. i hope you can get my point
