Device Overview

Summary

The Microchip USB4624 is a low-power, OEM configurable, MTT (Multi-Transaction Translator) USB 2.0 hub controller with 4 downstream ports and advanced features for embedded USB applications. The USB4624 is fully compliant with the USB 2.0 Specification, USB 2.0 Link Power Management Addendum, High-Speed Inter-Chip (HSIC) USB Electrical Specification Revision 1.0, and will attach to an upstream port as a Full-Speed hub or as a Full-/Hi-Speed hub. The 4-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 (non-HSIC) ports. HSIC ports support only Hi-Speed operation.

The USB4624 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. Flexible power rail options ease integration into energy efficient designs by allowing the USB4624 to be powered in a single-source (VBUS (5V), VBAT, 3.3V) or a dual-source (VBAT + 1.8, 3.3V + 1.8) configuration. Additionally, all required resistors on the USB ports are integrated into the hub, including all series termination and pull-up/pull-down resistors on the D+ and D– pins.

The USB4624 supports both upstream battery charger detection and downstream battery charging. The USB4624 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 USB4624 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
he USB4624 provides an additional USB endpoint dedicated for use as a USB to I2C/SPI interface, allowing external circuits or devices to be monitored, controlled, or configured via the USB interface.
