    help regarding H-bridge

    another thing.. should I use a higher voltage source to drive the TC4426 ..say 15v..than the 12v source for the bridge.. in that case what will happen? please advice. ..I did a quick test using just a single Nmos-IRF540 (as a switch) input was 0-5v pwm to driver IC and motor as load..the...

    help regarding H-bridge

    I'm now planning to make the bridge with MOSFETs.. the input will be pwm signals from a servo circuit..(0-5v) do you think the attached circuit will work..?? also I'm planning to use TC4426 instead of 4428..in the circuit..because I think 4428 is used incorrectly in the circuit (which I found on...

    help regarding H-bridge

    Thanks for the reply.. do you think ,if I use MOSFETs which are specifically designed for logic level input at 5v would function properly , if I replace the TIPs with mosfets in the same schematic ? mosfets like -- https://www.electro-tech-online.com/custompdfs/2011/10/RFP50N05L.pdf also can...

    help regarding H-bridge

    okay so I did the test.. results.. vcc 18.5v @ 3.5A motor voltage 14v @ 0.9A TIP 36s readings --- across Q1 (BC=0.6 , CE=0.09 , BE=0.7) Q2 (BC=0.61 , CE=0.09 , BE=0.7) TIP 35s readings --- across Q3 (BC=2.1 , CE=2.9 , BE=0.67)...

    help regarding H-bridge

    I increased the logic voltage to 12v @ 1A from 5v... and replaced the 2N2222s with TIP122 ... I am still getting around 1amp current on the motor leads...instead of 10amp...(in the original circuit)

    help regarding H-bridge

    I've already looked at that circuit...the problem with that circuit is that it has 4 inputs.. whereas I require only 2..thanks anyways

    help regarding H-bridge

    yes ..the logic level is at 5v.. but how do I increase the logic level to 12v without damaging the servo circuit(which runs at 5v)..

    help regarding H-bridge

    so will the same logic circuit work if I replace the TIPs with the mosfets..

    help regarding H-bridge

    firstly thank you for your speedy reply.. can you suggested which intermediary should I add between the logic and Transistors.. or can I use transistors which have a higher gain (eg- tip122 and tip127- gain of 1000 at 3A).. and make 2 or 3 h-bridges and connect them in parallel.. or what...

    help regarding H-bridge

    hey everyone...I need some help ASAP regarding my h bride.. I needed a bridge which would deliver about 10-15A current @ 12 - 14v DC so I made this circuit.. with reference to the schematic - I got these readings when I connected- 1. Vcc 18v dc (3.5 A) -- voltage across the motor leads...
