I think that IR2103 don't provide current for Gate MoSfet.Max current of IR2103 is 400mA.Due to Mosfet get hot.Perhaps,I will use IR2110 to replace IR2103.I need to search scheme using IR2110.
Thank u very much!
No,it's peak current.I think that I have some problem with power commutation board.Something don't run correct.Can anybody help me? :(

Wow.I didn't hear about this.What driver do I need?What specification do I need to notice?
To Centmo:Transition time low-high:1.5us,and high-low:1us
When i apply 24V to circuit,Peak current exceed 30A.I use ACS712-30A.
I suffer a same problem when I don't use PWM.High and Low are only on...
thank you,FVM.
I measured Vgs of High-side and Low-side .It's ok.
Switching frequency is 15Khz.
Sorry FvM for my English skill is so bad.I don't understand exactly mean of "an unbuffered boostrap driver IC".Can you explain this to me?
Hi everyone!
I am building an 1kw bldc motor controller.I have a problem with 6 MOSFET IRF3205.All Fet are so hot although motor run without load.I use IR2103 to drive Inverter.Bootstrap capacitors are 10uF.
Futhermore,I tried to run 250W bldc in bicycle electric and MOSFETs are cool.
I use...
