Understanding the advantages, limitations, and use cases of each technology helps engineers create reliable, space-efficient, and standards-compliant consumer products. Consumer electronics continue ...

Today's preferred rechargeable battery chemistry for small, lightweight, portable applications is lithium-ion. When it comes to power management for mobile phones, portable media players or navigation ...

An overcurrent protection device interrupts excessive current using fuses, circuit breakers, relays, and fault-sensing devices. Proper selection depends on fault current, coordination, and application ...

Overcurrent protection of conductors is an idea so simple that it is almost self-evident. Excessive current in a conductor results in rapid temperature rise, which damages insulation and creates ...

Consumer electronic products have become increasingly complex, compact, and power-dense. With these changes comes a heightened need for robust overcurrent protection strategies to ensure the safety, ...

The overcurrent protection requirements outlined in the NEC can be found in Art. 240, except as noted in Table 240.3. As we noted in Part 16 of our series on Electrical Services, the requirements for ...

For the PDF version of this article, click here. Protecting power transistors against overcurrent failure has always been a challenging issue in power circuit design. In order to protect against even ...

Requiring only a handful of inexpensive components, the circuit breaker in Figure 1 responds to both overcurrent- and overvoltage-fault conditions. At the heart of the circuit, D 2, an adjustable, ...
