A power supply, just like any other electronic circuit, can fail. Overvoltage protection requires few parts and is effective and relatively inexpensive insurance for costly electronics systems.

Overvoltage-protection circuits often protect electronic devices from power-supply transients, such as a rise from plugging in batteries or an external power adapter. Although these devices ...

While there’s no one-size-fits-all circuit protection solution, robust overvoltage protection is a necessity in virtually any application that connects to a power line. This article ...

Once the overload is gone, the PPTC cools returning the circuit to normal operation. This avoids the negative user perceptions that may result from frequent fuse replacements and circuit breaker ...

The MAX16010-MAX16014 from Maxim Integrated Products are overvoltage protection circuits designed for systems with high transient voltages such as those found in automotive, industrial ...

Instead, he opted to eliminate the LDO, and limit the charging voltage of the capacitor to 3.6V with a comparator-based overvoltage protection circuit.

Toshiba releases a new eFuse IC for repeated use that support functions to protect power line circuits.

Intersil’s new ISL9204 is a single-cell Li-ion battery charger chip with a 28V input voltage rating that eliminates the over-voltage protection circuit normally required in low-input chargers. The ...
