MIC5204BS

Overview

The MIC5204BS is a power management integrated circuit designed as an active terminator for high-speed memory applications. It operates within a supply voltage range of 3V to 6V and draws a typical supply current of 900µA. The device is housed in a surface-mount SOT-223 package, also referred to as TO-261AA. It supports an operating junction temperature range from -40°C to 125°C, ensuring reliability across various environmental conditions.

Feature Summary

• Designed specifically for DDR-II memory termination applications
• Operates with CMOS or TTL compatible logic control signals
• Provides stable voltage regulation for memory performance

Applications

• DDR-II Terminator
• SCSI-II Active Terminator
• Desktop, laptop, notebook, and palmtop computers
• Intelligent instrumentation
• Printers and disk drives

Procurement Notes

Verify the manufacturer part number MIC5204BS against official Micrel documentation to confirm specifications. Ensure the package type matches the required SOT-223 form factor. Check that the supply voltage and temperature ranges align with system requirements. Confirm authenticity through authorized channels to avoid counterfeit components.

Selection Notes

Select this component when designing systems requiring active termination for DDR-II memory interfaces. Consider the low supply current and wide operating temperature range for efficiency and reliability. Verify compatibility with SCSI-II standards if used in storage applications. Ensure the surface-mount package fits the PCB layout constraints.

Part Context

The MIC5204 series includes variants such as the MIC5204, which serves as a general-purpose active terminator compliant with SCSI-II specifications. The MIC5204BS variant is specifically optimized for DDR-II termination, reflecting the evolution of memory interface requirements. Both share similar functional principles but differ in targeted application support.

Replacement Considerations

Cross-reference with other active terminators from Micrel or compatible manufacturers. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement supports the same supply voltage range and package type.
