Lets hope that all cars get em real soon, Im sick to death of people with
non functioning brake
lights in Qld. Bring on the yearly roadworthies I say.

Unfortunately it will not solve the bigger problem of non functioning turn
indicators caused by many drivers inability to use the switch.
(or the even worse problem of their inability to use their mirrors, and turn
their heads!)

IME most cars are usually far better than those driving them.

Some people do manage to drive about without crashing into things,
however have no interest in fixing broken stuff on their vehicle,
so the head spins around in the hope they are getting away with it.

There really is all types of drivers on the roads. I agree inpections
are a good thing even if it means for some drivers stuff is broken
for only 364 days of the year.

A absolutely agree with you. Unless you're able to get the electronics
right to power the LEDs without wasting a large amount of electricity in
order to get the small amount actually needed for the LEDs, there's
going to be little or no gain.

Abso-bloody-lutely.

There's too much focus on "efficiency", when in the big picture, the
difference in total energy consumed is tiny in comparison with
making and moving a modern car around.

But given that the type of devices being discussed are intended to be
replacements for incandescent globes, the only light in a vehicle newer
than October 1991 in Australia that can be legally converted is the
interior light.

Get a GPS equipped 'phone on a plan. Stick it in a plastic bag.

Why would you want to do that?

GPS phones aren't that great. OK for hiking, perhaps like using a Garmin Etrex. But for car navigation you need
something that can be easily read,

Nope, at most you just glance at the current road name etc occasionally.

and heard, too.

Thats what you really want for most car use.

It needs to be able to be sat in a cradle.

I dont even do that with the TomTom, just sit it on the dash where
its a lot easier to enter a new destination on by picking it up than
with it stuck to the windscreen etc where its too far away for that.

Do any GPS phones, such as the N95 do that?

Yes, you can get a windscreen mount etc for the N95.

My 6110 Navigator does all that. And more. I can choose male of female voice for directions. The N95 is better
still. Bigger screen. Nonetheless, for these 54 year old eyes, I can read the maps without my reading glasses.

Of course, the Tom Tom is better, but is not as portable.

The 720 is, because its nice and thin with a decent big screen.
Still small enough to go in the pocket fine.

Except the phones still have one significant failing when using the other functions in that they're phones, so to
actually use them for a call you generally can't look at the screen at the same time as talking on a call without
extra devices to help.

Wrong. There's this new-fangled technology in 'phones now. It's called 'loudspeaker 'phone'. It's only been around
since the 1970s, so you may be unaware of it's existence.

And before you mention it, phones with mp3 player capability are illegal to use with the music player going and
'bud' earphones in your ears when driving.

Indeed. Not everyone who uses a mobile 'phone drives.

Also, these phones aren't cheap and their plans less so. The N95 for example, requires a subscription in order to
download the maps as you travel, and they also accumulate data usage which
you also have to pay for.

Bullshit. Both Nokias come equipped with maps for all of
Australia and more (for free). My 6110 costs me $50.00/
month with a shit load of 'phone calls (over $200.00 worth).

The data useage is still a significant cost if you buy
the phone outright and use a sim where you only
pay for calls and dont have any fixed monthly cost.


What data usage are you referring to? The 6110 will use data when you
activate 'assisted GPS' or whatever it's called to try to lock onto a
GPS signal quicker, but that can be turned off within the phone
settings. The maps can be downloaded using your PC then transfered
over USB. Or are you referring to general data usage? (web browsing
etc.)

See Page 36 of the Pdf download re 12.5Khz channel spacing, see link
within.
http://www.acma.gov.au/WEB/STANDARD/pc=PC_311117

The closing date for submissions is 18 July 2008.
Any increase in operating freq, will cause an increase in path-loss or
propagation loss. There are advantages ie more channels can be obtained.
A rough formula is: Prop-loss in dbs = 32 + 20log km (in kilometres) +
20log f (megahertz)
To find the difference in path loss due freq increase, keep the distance
the same, then include the original freq in use. Note the answer,..then
insert the new freq. Subtract first value from the second,..and you have
your loss due freq increase in dbs. To obtain a useful value which
conveys an easily, you need to understand decibels (db). For example 30
db is 1000 times the original figure, 3db is twice the original figure.
Google up a db to linear conversion.

But... but..
The mooted idea is to decrease the channel intervals - that won't change
anything but the 'requirement' for radios to be better at what they do in
terms of adjacent channels being a problem.

True, there will have to be reduced BW to stop adjacent ch splashing
dev.peaks into the ones either side. plus any reduction in channel spacing
will mean less deviation and therefore a degradation of Sig/Noise.

Will this mean the end of those piss poor Uniden radios that have a
front end so open you can hear every transmission in the 400-500MHz range??

Not just Unidens. GME's products are designed deliberately so that
additional listen-only channels can be programmed anywhere betweek about 450
MHz and 520 MHz. Dunno if that's by design or just a 'feature' that they
decided to use to commercial advantage. I'd say it's by design.

[Fred Bloggs]

So I would have thought that this would be a simple problem but the more
information I get the more I get confused......


I want to PWM a whole lot of LEDs. The current consumption of the bank of
LEDs is in the order of 15 Amps, at 12V.

For reasons I won't go into, my only option is to use a high side mosfet.

I have chosen an N-channel MOSFET (IRL3803) mainly because of its huge
current capability and very low on resistance of 7 milli ohms.

I am hoping to use PWM at a reasonably high frequency, say 20khz or higher,
and I want to use an efficient MOSFET driver IC that is designed for the
job.

I understand that to switch an N channel mosfet on the high side of the
supply line, I have to drive the gate with 10V **more** than the supply
voltage. This is correct yes?

This is where the question comes in. I am looking at the option of using the
IRS2001 to switch the high side fet. But looking at the datasheet, I am
confused. How can the IRS2001 generate a voltage greater than VCC without
actually being connected to the high side voltage????? There is no talk of a
charge pump in the description and in any case it does not know what
potential the fet is connected to..

Maybe it is not suitable for my application as the IRS2001 seems to be used
for switch mode power supplies? I can't make sense of the first diagram on
the datasheet.

here is a link to the datasheet:

http://www.irf.com/product-info/datasheets/data/irs2001spbf.pdf



OK so if the above IC is not suitable, I have been looking at the MAX621.

http://datasheets.maxim-ic.com/en/ds/MAX620-MAX621.pdf

This one looks to be more straight forward. But I'm not sure how this IC
will go with 20Khz switching. There are many **low side** mosfet drivers
that are in the 2 to 7 amp range to ensure that the mosfets are hard on or
hard off within a few nS. This one doesn't look like it will do anywhere
near that switching current.


Any other ideas for a high side N channel driver IC that packs a punch?

You're going about this all wrong, no one makes a dimmable LED supply
like this, the main reason being your excessive ripple current
resulting in unnecessary heating and exponential reduction in LED
lifetime. Another good reason for not doing it this way is to avoid the
fairly huge current spikes resulting from what will be a hefty
equivalent load capacitance producing enough EMI to be detected in
another galaxy. And you want to go to all this trouble to produce a crap
design because it's the only thing you understand. Do some background
reading: http://powerelectronics.com/mag/710PET24.pdf and put more
effort into your planning.

Why so high? If it's just for brightness control, you don't need that
surely?

if you strobe LEDs too slow, then it causes a strobe effect if there
is any movement... if you scan your eye past some LED rear car lights
you can get the strobe effect and it is very annoying... even if the
LED is not moving, your eye is always moving

I don't know how fast you need to pulse to avoid this but a few
hundred Hz is too slow. 5 kHz might be OK I don't know...

At 5 kHz you might get audio interference so that is a good reason to
go to 20 kHz.

Can you explain why you can not just break this down into multiple units
all centrally driven? say 15 units drawing 1amp each, or 30 units drawing
500mA?

It would be less convenient, but that is possible, and may end up being the
way I go.

I was thinking that would avoid the all eggs in one basket. if one unit
fails, it only takes out that fraction.

The other point is the frequency and duty cycle might be such that instead
of having to deal with an intermittent 15Amps, you could be dealing with a
consistent 5amps say or less.
