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
