The overwhelming majority of consumers want the
convenience of using fewer cords to power their cell phones,
MP3 players and other electronic equipment, as well as the
flexibility to charge portable equipment from their
computers. Because of this market demand, nearly all current
and future handheld devices will be able to charge from USB
sources. However, USB requirements present several circuit
protection challenges for designers of portable equipment.
Overvoltage, poor regulation, electromagnetic induction,
electrostatic discharge (ESD), incorrect wiring, and reverse
voltages are just a few of the events that a USB-enabled device may be exposed to.
