UC2907DWTR

Product Overview

The UC2907DWTR from Texas Instruments is a load share controller PMIC in a 16-SOIC surface-mount package. It is specified for a supply voltage range of 4.5V to 35V and a supply current of 6mA. The device is rated for an operating temperature range of -40°C to 85°C. Its package measures 0.295 inch wide, or 7.50mm, and is intended for surface-mount assembly. The part supports power-management designs that require a dedicated controller for load sharing among power sources.

Key Features

• Load share controller function for power-management systems
• Supply voltage range: 4.5V to 35V
• Supply current: 6mA
• Operating temperature range: -40°C to 85°C
• 16-SOIC surface-mount package with 0.295 inch (7.50mm) width

Applications

• Parallel power-supply arrangements where load current must be shared between sources
• Distributed power subsystems that use a dedicated controller to manage sharing among modules
• Surface-mount power boards that require a load-share controller in a 16-SOIC package

Design & Procurement Notes

When selecting the UC2907DWTR, verify that the controller supply voltage remains within the 4.5V to 35V range and that the 6mA supply current fits the system power budget. The -40°C to 85°C operating range should be checked against the expected operating temperature. The 16-SOIC surface-mount package requires a compatible PCB footprint and assembly process, and the 0.295 inch (7.50mm) body width should be considered during layout. Because the device is a PMIC load-share controller, confirm that the system requires load sharing among power sources.
