USB2512BI General Description

General DescriptionThe Microchip USB251xB/xBi hub is a family of lowpower,configurable, MTT (multi transaction translator)hub controller IC products for embedded USB solutions.The x in the part number indicates the number ofdownstream ports available, while the B indicates batterycharging support. The Microchip hub supports lowspeed,full-speed, and hi-speed (if operating as a hispeedhub) downstream devices on all of the enableddownstream ports.Features• USB251xB/xBi products are fully footprint compatiblewith USB251x/xi/xA/xAi products as directdrop-in replacements— Cost savings include using the same PCBcomponents and application of USB-IF Complianceby Similarity• Full power management with individual or gangedpower control of each downstream port• Fully integrated USB termination and pull-up/pulldownresistors• Supports a single external 3.3 V supply source;internal regulators provide 1.2 V internal core voltage• Onboard 24 MHz crystal driver or external24 MHz clock input• Customizable vendor ID, product ID, and deviceID• 4 kilovolts of HBM JESD22-A114F ESD protection(powered and unpowered)• Supports self- or bus-powered operation• Supports the USB Battery Charging specificationRev. 1.1 for Charging Downstream Ports (CDP)• The USB251xB/xBi offers the following packages:- 36-pin SQFN (6x6 mm) (Preferred)- 36-pin QFN (6x6 mm) (Legacy)• USB251xBi products support the industrial temperaturerange of -40ºC to +85ºC• USB251xB products support the extended commercialtemperature range of 0ºC to +85ºCApplications• LCD monitors and TVs• Multi-function USB peripherals• PC motherboards• Set-top boxes, DVD players, DVR/PVR• Printers and scanners• PC media drive bay• Portable hub boxes• Mobile PC docking• Embedded systems
