Microchip USB2514B-I/M2 Controller IC 4-Channel USB 2.0 3.3V-3.6V 36-Pin SQFN USB2514B-I/M2

Microchip USB2514B-I/M2 Controller IC is a high-performance USB 2.0 hub controller featuring 4 downstream channels. It operates at supply voltages from 3.3V to 3.6V and is housed in a compact 36-pin Small Quad Flat No-lead (SQFN) package. This device integrates MultiTRAK™ technology, which equips each port with a dedicated Transaction Translator (TT) to maintain consistent full-speed data throughput regardless of the number of active downstream connections. The controller fully complies with the USB 2.0 specification, supporting high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) USB protocols.

The USB2514B-I/M2 supports the USB Battery Charging specification Rev. 1.1, making it suitable for applications requiring charging downstream ports (CDP). Its flexible design includes PortMap for port mapping and disable sequencing, PortSwap for programmable differential-pair pin locations, and PHYBoost for programmable USB signal drive strength to recover signal integrity. This enhances PCB layout flexibility and signal quality in complex industrial and consumer electronic products.

Featuring full power management capabilities, the controller allows individual or grouped power control on downstream ports, helping reduce power consumption in multi-port USB hubs. Designed for surface mount application, the device’s physical dimensions are optimized for space-constrained designs with a height of 950 micrometers and a length of 6.1 millimeters. It operates across a wide temperature range from -40°C to 85°C, ensuring reliability in demanding industrial and commercial environments.

The device also incorporates Electrostatic Discharge (ESD) protection to improve robustness against electrical disturbances. The USB2514B-I/M2 acts as a direct drop-in replacement for the USB251x and USB251xA series devices, facilitating easy upgrades or replacements in existing designs.

This controller IC is ideal for industrial, laboratory, manufacturing, and consumer electronics applications requiring compact, flexible, and high-performance USB 2.0 interfacing solutions. Its multi-port capabilities support a broad range of USB devices while maintaining optimal data throughput and power efficiency.
