What this USB interface IC does and where it fits
The Maxim MAX1564ETE+ is a specialized interface IC designed for USB applications, handling the bus-side interface between the USB connector and the host controller or power management circuitry. It operates from a 2.7V to 5.5V supply rail, so it can run off a standard 3.3V or 5V USB bus supply without an extra regulator.
Package and mounting — what the board sees
Housed in a 16-WQFN with exposed pad (supplier package designation 16-TQFN 4x4 mm), this is a surface-mount part that needs a thermal pad on the PCB for both heat sinking and a solid ground connection. The exposed pad wants a via array under it for thermal transfer — without it, junction temperature climbs faster under continuous load. Standard reflow profiles for lead-free solder apply; the small 4x4 mm body places easily with no tombstoning risk if the stencil apertures are balanced.
Lifecycle and compliance — no obsolescence worry
ROHS3 compliant, so it clears the European material restrictions without an exemption. No PCN or EOL risk to track for the near term — this part is a safe BOM line for production builds.
