UCC39002DGK

Power Management - Specialized Overview

The UCC39002DGK is an advanced load share controller from Texas Instruments, designed for parallel power supply systems. It operates within a supply voltage range of 4.375V to 14.25V and draws a typical supply current of 2.5mA. The device supports an output current capability of 1.5mA and functions reliably across an operating temperature range of 0°C to +70°C. Packaged in an 8-pin VSSOP (DGK) format, it facilitates precise current sharing among multiple power sources.

Power Management - Specialized Feature Summary

• Implements active load sharing control to balance current distribution across parallel power supplies
• Features high-precision internal circuitry for accurate current matching without external components
• Provides robust protection mechanisms against reverse current flow and overcurrent conditions

Power Management - Specialized Applications

• Parallel redundant power supply architectures
• High-reliability telecommunications power systems
• Industrial equipment requiring continuous operation

Power Management - Specialized Procurement Notes

Verify the specific package variant and lifecycle status before procurement, as the UCC39002 family includes obsolete parts like the UCC39002P. Confirm that the DGK suffix corresponds to the required VSSOP-8 footprint and check for available alternatives such as the UCC39002DR if the exact part is discontinued. Ensure compatibility with system voltage ranges and thermal requirements during final validation.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring precise current sharing between parallel DC power sources. The VSSOP-8 package suits space-constrained PCB layouts. Consider the 4.375V minimum supply voltage for low-voltage applications. Evaluate thermal performance within the 0°C to 70°C operational range to ensure reliability under varying environmental conditions.

Power Management - Specialized Part Context

The UCC39002DGK belongs to the UCC39002 series of load share controllers, which are specialized PMICs for managing parallel power modules. This series enables modular power designs by ensuring equal current distribution. The DGK designation specifically identifies the small-outline VSSOP package variant, distinguishing it from through-hole or larger surface-mount options within the same functional family.

Power Management - Specialized Replacement Considerations

Public documentation indicates the UCC39002DR as a recommended alternative. Verify pinout compatibility and package dimensions before substitution. Check datasheet revisions for any functional differences between the DGK and DR variants.
