Actually, I’m really learning the whole process from scratch for this project – arduino programming, dead reckoning, sensors, motor drivers, suppression, pcbs etc. It’s a blast, but only having an hour here and there to work on it stretches things out. However, bear in mind that both need 10v or so gate drive. Why aren’t these in some kind of interactive graphic package so I could filter all of the parameters continuously and just have what I need pop out? At the moment, I have a working mockup of a prototype ha – using mechanical switch and a relay hbridge to emulate the switches in the car, relays for the motor hbridge, an accelerometer, hall sensor and magnets, a couple of tiny motors, etc. Terry – thanks for the intriguing idea of using the timer chip to drive the bridge.

It always takes longer than you expect, even when you take into account Hofstadter’s Law. Besides, bridges for four automotive motors are pretty darn expensive.

However, bear in mind that both need 10v or so gate drive. PDF This is my current candidate pair as orf9540 in the hbridge – anyone have better suggestions?

On you’re answer to my question, I’m not sure if you got my point. I’m assuming that the higher priced ones have some desirable quality but I can’t quite tell what it might be. The motors are volt automotive motors, so clearly the motor drivers have to accommodate lrf9540, but that other pchannel I datasheey appears to be a nice pair with your IRL logic level nchannel. I tried to read up on that last night but only had my tiny phone and couldn’t really get through the info.

Use Google Search box in upper right side of this page. So the price differentials at Mouser are not necessarily the same at other distributors.

So, perhaps you have different suggestion from these, but even within IRF, there are 8 or so versions in T package on Mouser. If I search for that part at RS http: Why aren’t these in some kind of interactive graphic package so I could filter all of the parameters continuously and just have what I need pop out?

Yes, that’s the fun! Need to read more. I’ll look it up If they’re all logic level, it should be doable, but I guess I need to carefully add up the current consumption of all of the elements I need to drive. Read times previous topic – next topic. Not certain of that, but will do some checking this weekend.

MarkT Brattain Member Posts: Their Rds on currents seem fairly different, so should I expect materially different motor speeds with this pair speed isn’t really that important to this application?

Please do not ask for unpaid help via PM, use the forum. It’s a blast, but only having an hour here and there to work on it stretches things out. I suppose it can be put down to different vendors having their different reasons for price points inventory, special source prices, shipping costs, marketing, etc as opposed to some technical advantage.

IRF9540 Datasheet

Some of the annotations were hard to read, but one nchannel mosfet, IRL, was called out can’t read the other one and it looks really nice with an Rds on of only 4. You’re datxsheet to get a precise match between the specs of N-channel and P-channel complementary mosfets, or between NPN and PNP complementary transistors, because the manufacturing processes seem to make it easier to get the best specs datasehet the N-channel and NPN versions.

You can do a lot better than this. The and are a reasonable match. I have 4 motors and 4 relays in the plan, and I don’t think I need PWM so when they’re running, they’ll just be flat out.

Terry – thanks for the intriguing idea of using the timer chip to drive the bridge. I can’t understand how to easily pick a better pairing as slogging through the part selectors and their crappy rows and columns is very slow going. Regards, Terry King terry yourduino.

Formal verification of safety-critical software, software development, and electronic design and prototyping. I’ve been looking at the parametric charts, but honestly my eyes keep crossing and I’m not spotting anything obvious. Per your earlier comment zoomkat it’s datasbeet a challenge. I’m trying to figure out what accounts for the price difference
