Recently i've noticed that my supplier doesn't carry anymore IRS21844STRPBF, but only IRS21844SPBF.
And there is difference.
Dual MOSFET Driver IC, Half Bridge, 10V-20V Supply, 2.3A Out, 270ns Delay, SOIC-14

vs
MOSFET Driver, Half Bridge, 10 V to 20 V supply, 1.4 A out, 270 ns delay, SOIC-14
https://uk.farnell.com/infineon/irs...bt-driver-half-bridge/dp/2710021?st=irs21844s
I've bought couple of the IRS21844SPBF, but they seem to be much more fragile and picky, die more often and so on and so on. I'm not pleased with the new ones. I had 2 chips that died just of pure randomness.
There is almost 1A of current output difference. Is this something to consider or ?
Anyone has info on this ?

It looks to be that one is titled for the low short circuit current rating while the other is titled for the high short circuit current rating.
Otherwise same datasheet.
Otherwise same datasheet.
I used only the IRS versions for the last few years I worked. I did have some failures on installation if I wasn't careful but they were otherwise reliable.
There are minor differences in specs but they're supposed to be perfectly good subs for the IR version.
On the datasheets I found, the current ratings were the same.
