In summary, automotive, industrial, and avionic systems suffer from high voltage power supply surges due to their harsh operating environments. Shielding electronics from these surges is critical for safe, reliable, and continuous system operation. Traditional overvoltage and overcurrent protection relies on a combination of discrete components such as transient voltage suppressors or TVS, fuses, capacitors, inductors, and diodes. The discrete solution is simple but comes with its downsides. Linear Technology’s Surge Stopper products solve the deficiencies of the TVS and fuse based shunt circuit. The low-profile surface-mounted Surge Stopper solution enables a compact system form factor while the accurate voltage and current regulation loops minimize overdesign and reduce cost.
