11 Ways to Protect Your Power Path

A power switch provides an electrical connection between a voltage source (or ground) and a load (any circuit), serving power across multiple voltage rails and protecting subsystems from damage. This e-book describes methods to protect your power path from overcurrent, overvoltage, reverse current, reverse voltage, inrush current, automotive load dump and other faults. This e-book also includes several power switch topologies with different functions that address various applications.

Topics include:

  • Controlling, blocking and monitoring current
  • Adjustable current limit
  • Protecting against reverse polarity, short circuiting and overvoltage
  • Overtemperature conditions and thermal shutdown and protection
  • Power-good and enable signals
  • Safely driving an inductive load
  • Automotive load dump
