MAX14691
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 p MOSFET, the devices also protect downstream circuitry from voltage faults up to +58V, -60V (for -60V external p FET 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. Additionally, the devices feature a dual-stage, current-limit mode in which the current is continuously limited to 1x, 1.5x, and 2x the programmed limit, respectively, for a short time after startup. This enables faster charging of large loads during startup. The MAX14691- MAX14693 also feature reverse-current and overtemperature protection. The devices are...
