MAX17525EVKIT# by Analog Devices

High-Accuracy, Adjustable Power Limiter


The Olympus series of ICs are the industry’s smallest and robust integrated system protection solutions. The MAX17525 adjustable overvoltage, undervoltage, and overcurrent protection device guards systems against overcurrent faults in addition to positive overvoltage and reverse-voltage faults. When used with an optional external pMOSFET, the device also protects downstream circuitry from voltage faults up to ±60V (for -60V external pFET rating. The device features 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 MAX17525 also feature reverse-current and overtemperature protection. The devices are available in a 20-pin (5mm x 5mm) TQFN package and operate over the -40°C to 125°C temperature range.
