Microchip USB 2.0 Hub Controller IC, 36-Pin QFN

Microchip USB 2.0 Hub Controller IC is a power-efficient USB 2.0 hub controller integrated circuit that provides scalable USB port expansion with 2, 3, or 4 downstream port configurations. It is supplied in a 36-pin QFN package measuring 6 x 6 mm, offering a compact footprint for space-constrained designs.

Overview

The controller is intended for applications that require low power consumption and a small footprint, including consumer electronics and mobile devices. All variants share the same 36-pin QFN package, and the device is designed for straightforward integration into new designs.

Key Features

• MultiTRAK: Multiple transaction translator providing one translator per port.
• PortMap and PortSwap: Flexible port mapping, disable sequencing, and programmable USB differential-pair pin locations to simplify PCB layout.
• PHYBoost: Programmable USB signal drive strength to help maintain signal integrity across different board designs.
• Power Management: Individual or ganged power control for each downstream port, with support for a single external 3.3V supply.
• Integration: Integrated USB termination and pull-up/pull-down resistors, plus an on-board 24MHz crystal driver.
• Compatibility: Footprint compatible with USB251x/xi/xA/xAi product families, allowing direct drop-in replacement.

Reliability and Compliance

The IC provides 4KV HBM ESD protection (JESD22-A114F) for both powered and unpowered states.
