New 4 Channel Highside driver

[badger1666]

question:
how do you set up current drive on these drivers ??
on the die4drive for example there is a monitor pin that you put a multimeter on
to read drive current

any way i am in for one let me know when they are ready

Simple: Connect an Amp meter directly to the outputs. Best to do it at 5V supply as it will heat up the FETs quite a bit

Hey T.... wouldn´t it be better to use a heatable dummy load, to avoid the FET heatup and convert the measurement to a voltage?

Sure, a dummy load would be nicer to the FETs, but it is less accurate. As the dummy load heats up, the resistance (and therefore the voltage) will change.

An Amp-meter in series with a dummy load would avoid this though.

Aha! .... I knew there was a good reason to include a TECdriver on the board ..LOL..

I, too, am in for one of these when ready. I have one of Edison's red modules on the way and he said this will be the best driver for that particular module.

UPDATE:

The PCBs has FINALLY left customs, and will be delivered to me Monday!

The driver I use (also with blue beam, supression) made by a very skilled member of this forum uses a onboard SMPS to set power to the driver just above the Vop of the diode to get a very efficient driver.

Hm, that smells like a class H audio amplifier. Efficient yet lightweight. Me like.

this is probably a stupid question, but could i power 2 lpcs and a 445 and not use the last channel or even just two diodes?

Sure, you can use as many (or as few) channels you want
