There is a internal relay that can connect test (signal) to Common.

So how have you done it Curtis on models after the Pro Track?
93
If in doubt always compare against a known good device.
But as Curtis says any resistive element in the trace rather than the usual diode knee could indicate a problem.
But as the MIP0221 has internal resistors the only way to be sure is to compare against a know good one.
See data sheet:- http://images.100y.com.tw/pdf_file/31-PANASONIC-MIP0223SC.pdf

Hello Bert,
The MIP0221 is an interesting component. It has quite of bit logic that drives the control (gate) pin of the power MOSFET connected to the drain and source pins. I will caution you to use lower Tracker voltages when testing as power MOSFET devices can be sensitive to reverse (negative) voltages. Keep the voltage below 5V and you should be okay.
It is difficult to generalize what a good or bad signature will look like so it is best to look at the signatures of several good devices to establish a baseline of good information. This will help you decide when you have a bad one. As with most semiconductor components, always suspect it is bad if you see any resistive change in the signatures.

Hello Huntron users.

I have a huntron 2800 and i want to test a mosfet ic the mip0221
I think is defect but what signature for this mosfet ic or mosfet is good or bad signature.

I hope somebody can help me.

Thanks anyway..

Greetings Bert from the Netherlands...

A relay would work as well but controlling it when you need it would be more of a challenge.

I take it that the Pro Track could do the same thing with the addition of a MOSFET on the input with the gate connected to the  Pulse Generator or external signal source to momentarily ground a troublesome jitter caused by a capacitor.

The Drain feature will work with all current design Trackers meaning the Model 30, 2800/2800S and 3200S. It is more of a Tracker feature than a Prober feature.

I take the " Drain feature is only available on Workstation 4?
Sounds useful, any more features like this on Workstation 4 using just a Huntron and Scanner,  no Prober?

I appreciate your company has to get back the 1000's of $'s invested in your Test Equipment & Software.
But is Workstation 4 the best program to used if a Prober is totally out of the the question.
Is just using a Pro Track and Scanner or the later model with scanner built in quicker and more straightforward using workstation 3.54. Probably not the best question to ask someone who wants you to buy workstation 4!!
