Complete Guide to Electronic Protection Circuits
Overvoltage Protection. A "crowbar" circuit (shown in Figure 1) can protect your device from overvoltage. In normal use, the 12V supply goes to the output via the reverse protection diode and fuse. The Zener diode is chosen to be slightly higher; in this case, 15V. When the input voltage reaches 15V, the Zener conducts, setting up a voltage across R2.
Popular Battery Charger ICs for Lithium Battery Charging and Protection
A USB charge input can charge the battery and power the system from a USB power source. When powered from USB or the DC input, system load current peaks that exceed what can be supplied by the input are supplemented by the battery. The MAX8903 also features overvoltage protection, charge status and fault outputs, power-OK monitors, and a ...

To prevent this, you must place a diode in series with the input: simulate this circuit. So when the input is shorted to ground this series diode (D2 above) will block current flow. When the input is present the diode will allow current flow so the system will run normally. If I have a 28V 10A power supply, I need to choose 10A diode? Please ...

Input Protection
Input protection is implemented in power supplies and DC/DC converters to ensure safe operation. The input fuse fitted within a power supply is not intended to be field-replaceable, it is rated such that only a catastrophic failure of the power supply will cause it to fail. It will not be cleared by an overload as the power supply will have some other form of overload protection, …
