You can use a push button to simulate the door sensor, use the one you have not wired up. You will need a pull up resistor, you can either use a external 10K pull up resistor or enable the internal pull up on Port B. Wiring the processor reset to port RB5 is not what the question meant, wiring the processor reset to RB5 (...)
Wrong. I/O and MISO (SDO) is push-pull output. Can't be connected together to prevent contension.
1. Enable clock for timer 2. Setup the timer as timebase for PWM 3. Enable clock for GPIO and AFIO 4. Set IO as AFIO output push-pull 5. Setup PWM 6. Enable timer 7. Switch on PWM pins Not really simple, but it is STM32))
To understand about saturation effects, we should know the core type and flux in regular operation. A push-pull transformer without any clamping or snubber might drive the MOSFET into avalanche breakdown in regular operation. Inrush current during output capacitor charging will cause respectively higher avalanche energy which might be sufficient
Hello! If i like to give output from controller to input for another one IC means..? It really depends on the type of input and output. If the output is push-pull, then you don't need a resistor to input in the next processor. If it's open drain, you need a pull up. Etc, etc... Dora.
Hi, currently im making an IGBT protection for voltage inverters - by turning off PWM signal in right moment. Now im making PCB and because its my first big project I have some questions: 1. I want to use TLC3702 comparator, they say that it has build in push-pull.. so i dont need any other resistor for it to work (besides current regulations ofc
I opened this new thread because even though this thread is for Three Phase push-pull signals the method is different that is it uses PWM mode. In the other thread it used Half-Bridge mode. Also this is for Three phase Inverter. The other Three Phase thread was for Three Phase AC Induction Motor Drive. I am using PIC18F46K22 with 8 MHz Crystal a
You have not mentioned any topology is specific. By the way, the most common to find in commercial products is the push-pull for relatively low powers, and the full-bridge for above.
So my question is that, can I connect these isolated push-pull converters in series? It depends on how well these two outputs are isolated. At some point in the feedback regulation loop, there is a capacitative coupling. Better to forget the individual regulations of the converters and make sure that the trans
There are many approaches to make bit storage based on loop. For example, the circuit called "bus holder" that used in digital IO can hold a bit value. The circuit is a buffer with weak driver, with input and output connected. And strong driver with Hi-Z ability. To load data strong driver push or pull, to store data strong driver in Hi-Z. Or lat
Hello Everyone. I am gonna design a push-pull dc dc converter converting 48V to 330Vdc based on the Tahmid's blog as below. 132927 My questions are: 1) Do I have to use isolation in the feedback, for example through opto-couplers, to isolate the higher voltage secondary side from the primary side? Or will the above cir
The LT1533 should work fine from a 12V input, but its 1A current limit means 5V won't provide enough power. There are certainly many other off the shelf SMPS transformers you could use instead of the one in the reference design. But it's likely not necessary to use a specialty part like the LT1533. A push pull converter with proper snubbers, layou
p.s. full bridge drive will work a lot better at this power level... rather than push pull... also gives you more effective Cu on the Tx Yes indeed, but he is specifically wanting push pull, presumably because its low voltage and VERY high current at 3KW. That needs to be taken into account and presents some rather nasty (...)
Hi all, I'm using ADXL375 accelerometer sensor connected to STM32F103 microcontroller. I wanna enable the interrupt pin of sensor and connect it to one of input pins of microcontroller in sensor datasheet it is said that interrupt pin is push pull active high. now, the Question is that How should I configure the input pin of microcontroll
BJT are fast if not driven into saturation. In addition MOSFET gate driver must provide low impedance push-pull operation, particularly fast gate discharge. That's impossible with your single transistor high side driver circuit. Just helpless.
1. That part is meant to be used in a push-pull configuration. 2. It's meant to be used in class AB or C, which means that small signal matching is not going to get you the optimal output power. 3. How did you choose your gate bias voltage? 4. Is this, by chance, for MRI applications? Fortunately the MRFE6VP61K25H is a popular part with the HAM r
It appears you are not producing a sine wave but driving some kind of square wave to the MOSFETS. I assume you are using a center-tapped iron cored output transformer with some DC votage applied at the center and the MOSFETS go to the ends of the windings. If I'm right, you have three electrolytic capacitors across each sid
Presume "push-pull" refers to transformer push-pull (half- or full-bridge is push-pull as well). Usually leakage inductance spikes are absorbed by dissipative snubbers, e.g. RCD or diode + Z-diode combination. Use interleaved primary windings to make the leakage inductance between both (...)
Once again, there are 3 possible logic types are used: 1. push-pull 2. open collector/open emitter 3. tri-state You have to use second one. You will use LAT register to latch zero value, then switching the TRIS register you will be able to change between two pin states: 1. Forced low by low side mosfet 2. Released tri-state pushed hi (...)
Thank you for the reply. During the test we tried to increase and decrease the bias voltage. since we decrease the voltage it comes back to the stable state. It seems it works in on mode by reducing the bias voltage. Thank you ahsoopk, Actually this board is the test board of the transistor. And I think they have already c
