Hey guys,
I have equipment that has a DC bus of around 800Vdc. How can I make a circuit to read the voltage value and when there is no voltage on the bus, activate a relay.
I thought about measuring the voltage on the dc bus with an op amp and then using a voltage comparator to activate the...
In case the Max5389 power supply is 5V, can a 1N5908 or a 1N6373 help me?
In the TVS datasheet, I don't know very well which values are important and when the TVS does the voltage clamping
1665364488
What would be the TVS Diode options to protect the MAX5389 when it is powered by a 5V source?
Hello, guys I have a very simple circuit with a PIC16F628 connected directly to a digital potentiometer MAX5386. All powered by a 5V source through an LM7805.
Initially, I had a problem with the Max5386, which returned the resistance to the initial position, after I put a 100nF capacitor...
Hello guys, my friend needs the CI CA3240, but this item is missing from distributors (Farnell, Mouser, Digikey,...).
What would be the option to replace this CI in DPID format?
I noticed that on some occasions it goes back to the average bridge value, which is mentioned in the datasheet.
There is a 100nf capacitor in the power supply, on top of the IC, and today you have to change it to other values without success.
Finally, I placed two capacitors in parallel, one...
Guys, I made a simple project with a PIC16F877 and a MAX5389, which is a digital potentiometer. I'm just connecting the UP/Down and Inc terminals directly to the PIC.
Both the PIC and the MAX5389 have a 100nF capacitor next to the VDD and GND pin.
The PIC also drives a transistor, which drives...
I once saw a circuit in which there was a resistor with a value of 10K between pin 8 (softstart) and pin 16 (Vref). I spent weeks wondering why the use of this resistor, I could never understand. Does anyone have the idea why they put such a resistor?
Guys, I don't know if you know the equipment for plastic film treatment for the corona effect, called corona treatment.
This equipment is an H Bridge formed by igbts transistors and in the H bridge, we have a transformer that raises the secondary voltage to about 10KV and applies an electrical...
PICKit 2 - No Device Detected
Hello people,
I got 2 clone recorders. When I go to record or read something in any uc, the PICKit 2 Programmer shows the screen with yellow background with the message "No Device Detected".
I checked the board's components and didn't find the damaged one...
