Tthank you for helping, I have now TLP250 MOSFET driver, but my power supply for this project is multi-output 12 and 5 Vdc,
and the ground is not isolated so the anode ground pin3 and GUD pin5 also the load will share the same ground.is that makes the microcontroller not isolated? or there is a...
Yes it should be to the +12V not the ground I understand that .. I tried it and it's worked well .. But I didn't try it yet with pwm from uc..
I hope to work with PWM too.
Thank you
Thank you Brian, I just tried your suggestion and it works well but when the transistor base is fluting the Mosfet still work, so if i put a 10k pull up resistor to the gate can this solve this problem?. or there is another better solution? , also is this circuit will work well with PWM or not...
Thank you zasto , i just tried IRLZ44 and it’s getting very hot . Can you please upload the circuit of it maybe i have something wrong in the connection.
I think it is easier to change the MOSFET to a Logic level MOSFET, but can you please recommend me one..
this heater will work 24 hours with PWM and PID system so I need a good MOSFET.

Thank you Brian.
I'll try this and give you the feedback.
Thanks Klaus,
I think the problem is VGS in HA210N06 is 10V so it will never work with pic microcontroller. i just realized that.
but i still need help for chossing the best one for this application.
the gate is coneccted with RC2/CCP1 PIC 18F4685
Hello everyone,
I'm working on a project that controls 12Vdc 7Amp silicon heater pad using MOSFET.
I tried HA210N06 MOSFET with a heatsink but it doesn't work correctly, the heater doesn't get hot but the MOSFET is getting very hot, I tried another lower amper heater it's work but also not get...
