Part Number: UC3638 Hello,
Could I get the tolerance for the following dimensions (see highlighted image)?
Need the Min/Nom/Max for the project I'm working on.
Thanks!
Part Number: UC3638 Hi,
We are working on very old project concerning a DC motor drived by UC3638.
This design was realized by a subcontractor and we didn't have access to al documentation.
Could you perform an internal review ?
I could send…
Part Number: UC3638 Hi,
I'm designing a TEC controller following the SLUA202A application note and I would like to do some simulations.
Is it possible to get the spice model of the UC3638 in order to simulate it with the full-bridge?
Thanks!
Part Number: UC3638 Hi team,
My customer is having an issue with UC3638-
On the first attached png file the amplitude of the triangle wave (scope C1) at UC3638DW pin CT drops to about 60% of normal for the two cycles on either side of the center of…
Part Number: UC3638 Hi,
Now I try to drive TEC, the power is about 24V/10A. want to use PWM solution to drive it, I found that SLUA202A document describe it.
My question is that
-It can work with 24V?
-If I change MOSFET bigger, it can support…
Part Number: UC3638 Other Parts Discussed in Thread: DRV8876 , DRV8874 Hi
I am trying to look for an IC to control TEC(Peltier), below is the requirements:
1. Control the voltage and current direction (Change Polarity) with Microcontroller (Without…
Part Number: UC3638 I am using the UC3638 in the 20 pin SOIC package.
I'm using a single supply (+12V) driving an 'H' bridge as per the application note for the TEC controller.
The INV pin is driven via 100k from a DAC and 100k to COMP.
PVset is…
Other Parts Discussed in Thread: UC3638 In UC3638 , page no 6, Icmd net is connected to comp, inv and csout pin of Uc3638.
What is the purpose of ICmd and other point of Icmd net is connected to which point??
Other Parts Discussed in Thread: UC3638 In the UC3638 datasheet, the pin function description looks not consistent for SOIC-20 DW package and DIL-20 package. It looks like SOIC-20 DW package pin descriptions are not correct. Anybody can double check and…
