TUSB2046BIRHBRG4

Controllers Overview

The TUSB2046BIRHBRG4 is a USB hub controller manufactured by Texas Instruments, belonging to the TUSB2046B series. It supports the USB 2.0 standard with full-speed data rates of 12 Mb/s. The device features four downstream ports and operates within a supply voltage range of 3 V to 3.6 V, drawing approximately 40 mA of operating current. It is housed in a 32-VQFN package (5x5 mm) suitable for surface mount installation. The component functions across an industrial temperature range from -40°C to +85°C and includes integrated ESD protection.

Controllers Feature Summary

• Provides four-port expansion for USB 2.0 full-speed devices
• Integrates optional serial EEPROM interface support
• Includes built-in electrostatic discharge protection mechanisms

Controllers Applications

• Peripheral connectivity hubs
• Industrial control systems requiring USB expansion
• Consumer electronics interfaces

Controllers Procurement Notes

Verify the specific suffix 'RG4' against official documentation to confirm RoHS compliance status and lead-free characteristics. Ensure the ordering part number matches the required tape-and-reel packaging configuration. Cross-reference the datasheet revision history to validate current manufacturing availability and any potential form-fit-function changes.

Controllers Selection Notes

Select this component when a compact, low-power solution for expanding USB connectivity is required. The 32-VQFN package offers a small footprint suitable for space-constrained designs. Confirm that the 3.3 V nominal supply voltage aligns with the system power architecture. Verify thermal requirements for the intended operating environment within the specified temperature limits.

Controllers Part Context

This part belongs to the TUSB2046 family of USB hub controllers. The 'B' designation typically indicates commercial grade specifications, while the 'IRHB' suffix denotes the specific VQFN-32 package and reel packaging type. The 'G4' suffix generally signifies lead-free and RoHS-compliant manufacturing processes consistent with Texas Instruments standards.

Controllers Replacement Considerations

TUSB2046BIRHBT: Identical functional core but may differ in packaging or reel specifications. TUSB2046BIRHBR: Same package and function; verify if the 'G4' suffix is mandatory for regulatory compliance in the target application.
