Electronic Fuse for DC Short Circuit Protection
This is an electronic fuse that protects the load against short circuit.
Project Description
Relays must be chosen with a voltage value equals to the input voltage. Don’t omit using the 100uF capacitor with appropriate voltage value with respect to the input voltage. If you can’t provide, you can use C106 instead of BRX46.
You can adjust the current with using 10K potentiometer. If you will use the fuse with very high currents, lower the 0R6 5W resistor value (ex. 0R47, 0R33, 0R22 or 0R1). Watt value of the resistor should be increased also.

| Electronic Component Temperature Sensor |
Electronic components that are used for temperature sensors, among others: NTC, PTC, Thermostat, IC LM35 temperature sensor, temperature sensor IC LM335 etc. To create a series of simple electronics of the temperature sensor of the basic components of the temperature sensor, the component needs to connect to the transistors or Op-Amp as driving to the end of the circuit.

4x25W CAR AMPLIFIER TDA7381 ELECTRONIC DIAGRAM
4x25W CAR AMPLIFIER TDA7381 ELECTRONIC DIAGRAM
The extremely reduced components count allows very compact sets. The on-board clipping detector simplifies gain compression operations. The fault diagnostics makes it possible to detect mistakes during Car- Radio assembly and wiring in the car.
Absolute maximum ratings of IC TDA7295 IC
- Operating supply voltage = 18 V
- DC supply voltage = 28 V
- Peak supply voltage (t = 50 ms) = 50 V
- Output peak current Repetitive (duty cycle 10 % at f = 10 Hz) = 3 A
- Output peak current Non repetitive (t = 100 µs) = 4A
- Power dissipation, (Tcase = 70 °C) = 80 W
- Junction temperature = 150 °C
- Storage temperature = -40 to 150 °C
