MAX14721-MAX14723 High-Accuracy Power Limiters

Analog Devices MAX14721, MAX14722, and MAX14723 High-Accuracy Adjustable Power Limiters guard systems against overcurrent faults in addition to positive overvoltage and reverse-voltage faults. When used with an optional external p-channel MOSFET, these devices also protect downstream circuitry from voltage faults up to ±60V. MAX14721-MAX14723 features a low, 76mΩ, on-resistance integrated FET. During startup, these devices are designed to charge large capacitances on the output continuously for applications where large reservoir capacitors are used on the inputs to downstream devices.
