thanksPresuming that you mean 1MHz. You need some serious current into the gates of those MOSFETS to shift 63nC of charge in a very short space of time. OnSemi has a good selection:
C1 is plenty big enough, 100nF is the normal value for 100kHz.
pardon firstly, I looked signals on ır2110, not output , but I drive ır2110 with flip flop circuit .I controled that Flip flop circuit is true .after I tried another with ır2110 ,but not triggering. I am curious at the circuit true??My car won't run. Why does it not run?
Since we are not clairvoyant, you need to tell us how does it not run.
What do the various node signals look like?
You are correct - minimum spec for VIH is 9.5V, on a 15V supply. It’s not the best datasheet - it also says that logic inputs are compatible with standard CMOS/TTL down to 3.3V, so I guess that the threshold is nominally half Vdd, so it should work with 5V logic provided that Vdd is also 5V. Vcc, however, should be higher than that, at least 10V.today , I look at the circuit.I think that Vhi and Vli need 12-15v logic pulse.
what if do you use that how many volt for logic pulse???
