What the 5.5V to 60V input range means for your rail
The MAX17525ATP+ is an adjustable power limiter from Analog Devices, part of the Interface & Transceivers category, designed to sit between a raw supply rail and the downstream load as a current-limiting switch. Its 5.5V to 60V input range covers the common 12V, 24V, and 48V industrial buses, plus the 48V PoE and 54V telecom rails, with margin for transients up to the abs-max rating — no external clamp needed for most 48V systems. The 1.4mA supply current is the IC's own draw from the input rail; the load current is set by an external resistor, not by this figure.
