Product Introduction
The 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 of downstream ports available, while the B indicates battery charging support. The hub supports lowspeed, full-speed, and hi-speed (if operating as a hispeed hub) downstream devices on all of the enabled downstream ports.
Features
- USB251xB/xBi products are fully footprint compatible with USB251x/xi/xA/xAi products as direct drop-in replacements — Cost savings include using the same PCB components and application of USB-IF Compliance by Similarity
- Full power management with individual or ganged power control of each downstream port
- Fully integrated USB termination and pull-up/pulldown resistors
- Supports a single external 3.3 V supply source; internal regulators provide 1.2 V internal core voltage
- Onboard 24 MHz crystal driver or external 24 MHz clock input
- Customizable vendor ID, product ID, and device ID
- 4 kilovolts of HBM JESD22-A114F ESD protection (powered and unpowered)
- Supports self- or bus-powered operation
- Supports the USB Battery Charging specification Rev. 1.1 for Charging Downstream Ports (CDP)
- The USB251xB/xBi offers the following packages: 36-pin SQFN (6×6 mm) (Preferred), 36-pin QFN (6×6 mm) (Legacy)
- USB251xBi products support the industrial temperature range of -40°C to +85°C
- USB251xB products support the extended commercial temperature range of 0°C to +85°C
