It has low current handle capacity of sink source which is acceptable
But in as ir2110 is rugged and never below up
What would be in case of Fan7380 does it has almost same internal structure except timing issues.

I m using ir2110 for 110vac acim at 2khz pwm
Simple on off...
Datasheet is in attachment please solve my doubt
I have to use fan7380 for motor control acim

Fan7380

Right now i am n
Right now circuit is non isolated logic ground and power ground is star connected
If does fan7380 and ir2110 has same technique.
If i use COM side of...
I am worried about ground connection of low side and digital ground.
In ir2110 VSS and COM have different path
In FAN7380 there is no Vss or vdd
Bit worried about safety in digital side
Hello
I am running 3 phase ACIM from 100vdc bus and amp around 2.2a
I am using edge aligned mode of pwm, IRF640 MOSFET & IR2110
my question is does center aligned pwm is better for motor control and provide more life to mosfet???
I saw many italy made card in which they people use mosfet...
May be i could not put my question here proper way. Thats ture idealistic math and real circuit never same.
My problem was simple
Under id= 7amp (lets say now continuous load)
And room temperature 40 degree Celsius whats would be junction temperature and case temperature.
I do not know where i...
Actually i am saying if current goes upto 7amp for short duration like 10usec
1649401116
Actually i just consider the situation if current goes high for 10usec
Thats my answer.
I just ask because i have to protect mosfet from failure. Rise in Tj become cause of failure during sudden rise in...
I just want to know if ID: 7AMPS pluse of 10usec
Ta:40°c
Then what would be estimated(not exact) temp of TC &Tj
Or another to avoid all calculation i just follow this table.
Switching frq :2khz
Continuous current of acim is : 2amp
I am assuming 7amp over current condition under any fault thats why i want to know about the Tj under 7 amp condition
1649361882
Due to cost reason i have only mosfet option
1649362538
Can someone tell me Rth(j-c) : 1°c/w what it does...
I am working on motor control acim motor(only speed control) with switching device IRF640 with DC bus 90v.
My question if what would be Tj temp when
ID= 7amps
Rdson: .18mohm
Ta= 40degree Celsius
Rth(j-a): 62c/w
P=IxIxR
P= 7x7x.18=8.82
Tj= Ta+Rth(j-a)XP
Tj= 40+62×8.82
Tj= 586.84
Please help me...

I know about this solution. But customer need only 3 wire input means only 3 phase 90vac and 3 wire for motor only. Bunch of wires confuse to customer. Thats why i work for low cost bulid in supply.
In this board capacitive supply continously on but only switch on/off motor by ZCD traic circuit.
Till now i have add my little experience in hardware design please suggest me any possible change
1646389514
Till now i have add only 100ohm 2w resistor and drop on it is 5v under stand still and...
Any suggestion i just have switch on and off motor maximum motor run time is 8 sec motor off time 2sec nothing else.
I am following suggested circuit in datasheet
BTA16A-600 never below from last 6 month only capacitor and resistor below of psu
