    MOSFET buring out while switching

    Refer to the circuit, please. This is the circuit that controls an industrial horn. When the horn is turned on, it can draw up to 7A of current. The issue is that sometimes the MOSFET fails. All of the buzzers we use have the same specs. Help resolving the problem.

    [SOLVED] Controlling Inductor using NPN

    The input will be 12VDC or 24VDC. NPN operating time will be 100ms between ON and OFF condition. Shall we use fast recovery diodes instead of 1N4007.?

    [SOLVED] Controlling Inductor using NPN

    Hello friends Please see the picture that is attached. The load may be turned ON/OFF with a 100ms delay based on the controller's signal. Instead of a mechanical relay, we used an NPN transistor. It is now operating OK, however the bridgre rectifier temperature is occasionally rising when the...

    [SOLVED] Flashing ESP32

    Main File: #include <Arduino.h> int LED_BUILTINS = 2; void setup() { pinMode(LED_BUILTINS, OUTPUT); } void loop() { digitalWrite(LED_BUILTINS, HIGH); delay(1000); digitalWrite(LED_BUILTINS, LOW); delay(1000); } Platforum.ini [env:upesy_wroom] platform = espressif32 board =...

    [SOLVED] Flashing ESP32

    Hai, Using VS Code with Platforum IO to program ESP32-WROOM-32E.After Compling the code .bin file is generated under .pio\build\upesy_wrover.After generating the bin file,used NodeMCU-PyFlasher-4.0 to flash the ESP32 clip.Flash mode is DIO. Flashing completed successfully but there is no output...

    [SOLVED] Shift Register Issues

    Sorry picked an wrong word.When MCU is removed the outputs of shift registers in low state.If MCU is connected with shift register means for the outputs are going to high state at initial time only.After running the port configure sequence outputs in shift register in low state

    [SOLVED] Shift Register Issues

    Removed the IC from board and tired with shift register alone.During that time there is no output is switched ON.But when IC is used means,the outputs going to high at time required to MCU configure.When the 1st sequence is started after port configure of MCU,there is no error in shift register.

    [SOLVED] ULN2803 Interface

    Hai, There are two power supplies +5VDC and +12VDC. +5VDC is given only to MCU and other ICs.Relays are operated by seperate +12VDC.Both power supply having separate GND. I'm using ULN2803 to operate relays. My doubt is shall we connect the ULN2803 directly to MCU through resistor to driver...

    [SOLVED] Shift Register Issues

    Hai, Already discussed regarding this in below topic. https://www.edaboard.com/threads/shift-register-issue.395413/ Please refer the image. For Example:When power failure occurred and power resumed means,some times outputs are switched ON with previous state without enabling the OE pin.How to...

    [SOLVED] Connecting Grounding

    There is an power circuit in that machine.+12VDC is given as input and 2kv is generated on another side of power circuit.Current consumption of whole circuit will less than 1A. And providing earth to board by using multiple points(using mounting holes) is better or through single point is better.?

    [SOLVED] Connecting Grounding

    Hai, While grounding the PCB Method 1:Created an PCB,mounting hole with PAD and conductive material is used to mount the PCB on machine.Whole body of the machine is connected to ground.continuity between the ground and earth is available while checking with multimeter. Method 2:Created an...
