    H-Bridge COmplementary Transistors--Plz help in selecting them

    Hi audioguru! well! very very sorry for not putting up the diagram. here is the diagram Now this is the circuit which i want to use. thanks for supporting IRF540. its available in our area. But i have read somewhere on a  website that IRF9540 is almost a complementary P-channel mOsfet of...

    H-Bridge COmplementary Transistors--Plz help in selecting them

    hi guys! following is the picture of the H-bridge i want to use. Please keep this thing in the mind that im ussing this H-bridge for some really powerful motors that will be requiring around 4-5 A of current each.  So. i will be using one circuit for each motor. But the problem is this that in...

    Please help in the MOSFET driver

    Hi tony! Im greatly surprisde by ur answer. Sorry to say but i have successfuly driven a DC motor with this circuit of TC4424. Now please tell me that can i drive a more powerful DC motor(whose current is about 4A) with TC4420 by using two of them (one for each side) or will this TC4424 will...

    Please help in the MOSFET driver

    Hi guys! well i was using the following schematic for my H-bridge in order to drive a DC motor. This circuit is fine for a small motor. Now i want to use a relatively more powerful motor whose current can get increased from 3A. The TC4424 can only support a peak current of 3A. So using this...

    Shutter Mechanism

    HI ante! thanks for that help. well! i want to show u exactly what my tunnels look like. below i have posted a figure which can describe that. U see the tunnels are not standing upright, they are rather in the form of an inclined plane. there are two tunnels. We will insert the balls from the...

    Shutter Mechanism

    Hi guys! well! suppose that i have a tunnel that is having a slope i.e. When a tennis ball is inserted from its top end, it automatically floats to the bottom end and comes out of the tunnel due to slope. Now if i insert, lets say 8 balls in that tunnel one behind the other, so the balls will...

    Help me in finding the POWER MOSFET Driver

    Hi guys! well! im using a 3A dual High Speed Power Mosfet driver named as TC4424 in a circuit of H-bridge to control a DC motor. Now as i have written it can only support a peak current of 3A. I want to run a motor whose peak current is greater than 3 A but less than 5A. What should be the...

    Problem in an H-Bridge

    Hi Guys! well! i have made the following H-bridge which is made up of BJTs. Im providing it with the PWM through my PIC. The problem that im facing here is this that my DC motor is just not running with this circuit. The PIC seems to be working fine but there is no motion in the motor. When i...

    Does Infra red get reflected from white surface?

    Hi guys! well me, in a robot thinking of using an infra red LED and a detector to track a line made up of a white reflector tape often used in cars. someone just told me that the infra red gets absorbed in a white surface and cannot get reflected. Is it true? if yes then what idea should i...

    amplifiers used in Radar Immunization ??

    HI Guys! well! i have read somewhere that the waves generated by a primary radar adversley affect the electronic components of the vehicles that travel in the vicinty of the airport. To immunize these effects, TWT amplifiers and Class C amplifiers are used. I want to ask you two questions...

    12V to 5V

    thanks a lot Audioguru! but one question of mine still remains intact. What should be the values of Cin and Cout in order to make it suitable for 5.2V @ 6A. should i go with 10uf because datasheet says that for Cout, 10uf is a good starting point. but i didnt find any clue regarding Cin. can...
