System power protection ICs prevent field failures and unexpected downtime by mitigating the harmful effects of reverse voltage, hot swap, overvoltage, overcurrent, and overtemperature fault conditions frequently encountered in industrial, medical, e-mobility, and other environments.
Our complete system protection ICs integrate back-to-back MOSFETs for robust protection with nanosecond response times. Our robust, compact solutions feature:
- Inrush current limit
- e-Fuse/overload limit
- Reverse voltage
- Power limit
- Thermally controlled current foldback
- Current monitoring
