Complete System Power Protection ICs

Protect Your Power System Against Faults with Single-Chip Solutions

Maxim's Complete System Power Protection ICs prevent field failures and unexpected downtime by mitigating the harmful effects of overvoltage, overtemperature, and overcurrent fault conditions frequently encountered in industrial environments.

System protection ICs integrate back-to-back MOSFETs for robust protection with nanosecond response times. Our robust, compact solutions protect against overvoltage, undervoltage, reverse voltage, thermal fault, and reverse current conditions. Features include inrush current limit, overload current limit, power limit, thermally controlled current foldback, surge protection, current monitoring, and flexible fault management options.
