(100A / 13.8v) IR2110S_H_bridge "no" runing...

[Newtoybrazil]

Hello everybody in the forum.

I have used the much informations existent here in my littlest projects and circuits tests...

In this moment I have one "BOMB" in my hands! I assembled one (H_BRIDGE) to
control one motor in "13,8v" for a little electric car but, this circuit not work.

I'm probably doing it wrong ... During testing ... See the circuit used in the figure below ...

On the future this circuit will be drived with logic board based in one PIC microcontroller but in this moment I be testing with common switches...

I never used the IC "IR2110S", and do not know if this can be triggered only by reversing the levels in their inputs or pulses is necessary to make the engine run and reverse...!?

When I turn on the circuit, the voltage levels on the outputs of the drivers do not change.

And if I try to reverse the direction... The transistors begin to heat up ...

Have tested the transistors because I thought it could have killed them, however, nothing it's all ok.

Also replacing the two IC drivers however, nothing work ...

Someone has set up a circuit with this IC? Could give me some information?

I read this documents:
**broken link removed**
**broken link removed**
But, no helped me so much ...

PEACE, HARMONY and HEALTH, from BRAZIL.

Thanks for any help and information.



This is a first prototype board...

Add 100ohm resistor between gate and source of each transistor.

Again, thanks for your attention, sorry a little explanation for the circuit.
Receive all my respect and gratitude.

There was helpfull with added resistors?
