Analog Devices / Maxim Integrated MAX17525 High-Accuracy Adjustable Power Limiter

Analog Devices MAX17525 High-Accuracy Adjustable Power Limiter is an adjustable over voltage, under voltage, and over current protection device. This Analog Devices device guards the system against over-current and positive over-voltage and reverses voltage faults. When used with an optional external pMOSFET, the device also protects downstream circuitry from voltage faults up to ±60V. The device features a low, 31mΩ, 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. 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 for a short time after startup. This feature enables faster charging of large loads during startup.
