Microchip's USB251xB is a family of versatile, cost-effective, and power-efficient USB 2.0 hub controllers. Leveraging Microchip's innovative MultiTRAK™ technology that delivers industry-leading data throughput in mixed-speed USB environments, the USB251xB family is a USB port expansion solution for applications that demand ultra low power and a small footprint without compromising on performance. Well-suited for consumer and mobile applications, all members of the USB251xB family are available in a space-saving package. The common 36-pin package shared among the 2/3/4 port hub controllers measures only 6x6 mm and provides an ultra small footprint for space-constrained designs while allowing scalable port expansion from two to four ports. Over 30 programmable features including Microchip's unique PortMap, PortSwap, and PHYBoost are designed to aid system designers in simplifying PCB layout and optimizing bill-of-material cost. Every downstream port of the USB251xB hubs can be enabled to support USB Battery Charging 1.1 specification as a Charging Downstream Port (CDP). A CDP provides universal battery charging capability to a compliant mobile phone or portable electronic device using a standard USB port. The USB251xB supports an extended operating temperature range of 0°C to 85°C. The USB251xBi is designed to meet -40°C to 85°C industrial temperature requirements. Note that the "M2" product versions are targeted for new designs. The M2 products are manufactured on the latest production flow offering improved efficiencies and capacity. No product versions of the USB251xB are near the end of life, with all versions maintaining full production release status.

The USB2532 is fully compliant with the USB 2.0 Specification, USB 2.0 Link Power Management Addendum and will attach to an upstream port as a Full-Speed hub or as a Full-/Hi-Speed hub. The 2-port hub supports Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed hub) downstream devices on all of the enabled downstream ports. The USB2532 has been specifically optimized for embedded systems where high performance, and minimal BOM costs are critical design requirements. Standby mode power has been minimized and reference clock inputs can be aligned to the customer’s specific application. Additionally, all required resistors on the USB ports are integrated into the hub, including all series termination and pull-up/pulldown resistors on the D+ and D– pins. The USB2532 supports both upstream battery charger detection and downstream battery charging. The USB2532 integrated battery charger detection circuitry supports the USB-IF Battery Charging (BC1.2) detection method and most Apple® devices. These circuits are used to detect the attachment and type of a USB charger and provide an interrupt output to indicate charger information is available to be read from the device’s status registers via the serial interface. The USB2532 provides the battery charging handshake and supports the following USB-IF BC1.2 charging profiles: * DCP: Dedicated Charging Port (Power brick with no data) * CDP: Charging Downstream Port (1.5A with data) * SDP: Standard Downstream Port (0.5A with data) * Custom profiles loaded via SMBus or OTP The USB2532 provides an additional USB endpoint dedicated for use as a USB to I²C interface, allowing external circuits or devices to be monitored, controlled, or configured via the USB interface.
