MAX14691–MAX14693 EVALUATION KIT AVAILABLE High-Accuracy, Adjustable Power Limiter General Description The MAX14691–MAX14693 adjustable overvoltage, undervoltage, and overcurrent protection devices guard systems against overcurrent faults in addition to positive overvoltage and reverse-voltage faults. When used with an optional external pMOSFET, the devices also protect downstream circuitry from voltage faults up to +58V, -60V (for -60V external pFET rating). The devices feature a low, 31mΩ, on-resistance integrated FET. During startup, the devices are designed to charge large capacitances on the output in a continuous mode for applications where large reservoir capacitors are used on the inputs to downstream devices.
