The MAX8586 is a single current-limited switch that controls up to 1.2A of current for powering USB applications. It has multiple protection features including thermal shutdown, internal current limiting, and reverse current protection. The IC meets all IEC specifications for USB ports and automatically shuts off when the output experiences a short circuit for more than 20ms, saving system power.
The MAX8586 is a single‑channel, current‑limited USB switch designed for USB ports, hubs, computers, PDAs and docking stations. It provides up to 1.2 A of load current, programmable current limit, reverse‑current protection, thermal‑shutdown, fault‑blanking and an optional auto‑restart feature. The device is supplied in a compact 8‑pin 3 mm × 3 mm TDFN package with selectable active‑high/low ON input.
The datasheet includes absolute maximum ratings, electrical characteristics, typical operating curves, pin descriptions, detailed protection mechanisms, and package dimensions. Ordering information for automotive‑qualified and RoHS‑compliant variants is also provided.
