MAX4080SAUA

MAX4080SAUA is a part from Maxim Integrated (now Analog Devices) in the MAX4080 family. The “SAUA” suffix identifies the specific package/variant of the device. The MAX4080 family comprises small, low‑power analog ICs used in power management, monitoring, and protection in portable systems.
A typical starter view:
- Role: voltage/current sensing, fault protection, or MCU supervision depending on the exact variant.
- Features: low quiescent current, fast response, and a protected/monitored I/O path suitable for battery-powered designs.
- Applications: battery packs, power managers, motor drivers, and microcontroller reset/watchdog use.
For a precise introduction (pinout, electrical characteristics, thresholds, and package details), consult the official MAX4080SAUA datasheet. If you can share the datasheet link or confirm the exact function (voltage supervisor, current-sense/protection, etc.), I’ll tailor a concise summary.

Pin count: 8 pins (in the SAUA variant).
Function: MAX4080SAUA is a high-side hot-swap controller with current-limit protection. It limits inrush current, provides soft-start, and includes fault/shutdown signaling to protect a power rail when a load is connected or inserted.

MAX4080SAUA is manufactured by Maxim Integrated (Maxim Integrated Products, Inc.). Maxim is a semiconductor company specializing in analog, mixed-signal, and power-management integrated circuits; it now operates as a subsidiary of Analog Devices.

Typical application areas for MAX4080SAUA include hot-swap protection and inrush-current limiting for power rails in servers, backplanes, telecom/datacom equipment, and industrial automation; automotive and battery-powered systems requiring safe power-on sequencing and rail protection; DC/DC converter protection and general power-distribution protection in consumer electronics. It provides current limit, soft-start, and fault handling to protect connectors and rails during plug-in and fault conditions.

It’s in an 8-pin Small Outline IC (SOIC) package.
