Prioritized PowerPath Controllers; LTC4417/4419/4420 - Video Product Brief

Pinkesh Sachdev - Product Marketing Engineer - Mixed Signal Sep 1st 2016
  PowerPath™ prioritizers are low operating current circuits that provide backup switchover power for keeping critical circuitry alive during brown out and power loss conditions based on a user-defined priority. Priority is defined by pin assignment, with V1 assigned the highest priority and V3 the lowest priority. ...

Surge Stoppers: Overvoltage & Overcurrent Protection ICs - Video Product Brief

Pinkesh Sachdev - Product Marketing Engineer - Mixed Signal Aug 25th 2016
  Historically, overvoltage and overcurrent protection (e.g., load dump protection) was achieved using bulky capacitors, TVS diodes and fuses, but this discrete solution consumes a lot of real estate, and does not offer continuous operation through transient events. Linear Technology's family of High Voltage Surge ...
