Description
MAX5085ATT+T is a Maxim Integrated hot-swap/current‑limit controller. It drives an external N‑channel MOSFET to protect a PCB when power is applied, limiting inrush and overload current in the power path. Core features typically include adjustable current limit, soft‑start to tame inrush, undervoltage lockout, overcurrent/overvoltage protection, and a fault/status output. It’s used in power supplies and hot‑swap circuits where boards plug into live rails.
Operation (high level): the device monitors the sense path (sense resistor) and modulates the MOSFET gate to keep load current within the set limit; on fault it asserts the status output (and may latch or auto‑retry, depending on mode).
Suffix ATT+T denotes packaging/temperature options (see datasheet for exact meaning of the variant you need). For exact pinout, electrical specs, and application notes, consult the MAX5085 datasheet on Maxim/Analog Devices’ site.

Pinout
I don’t have the exact pin count loaded for MAX5085ATT+T. The pin count depends on the package (e.g., 16-pin TSSOP vs. 20-pin TQFN). The MAX5085 family is a high-side switch with current limit and fault/shutdown features. Please provide the package or a datasheet link for the precise pin count and pinout.
