MIC5165YMM

Overview

The MIC5165YMM is a dual regulator controller designed for high-speed bus termination in DDR3, GDDR3, GDDR4, and GDDR5 memory applications. It operates within an input voltage range of 750 mV to 6 V and requires an operating supply voltage between 3 V and 6 V. The device draws an operating supply current of 15 mA. Packaged in a 10-lead MSOP format, it supports temperatures from -40°C to +125°C. This component provides a simple, low-cost solution for JEDEC-compliant memory termination control.

Feature Summary

• Dual regulator controller architecture optimized for high-speed bus termination
• Supports multiple memory standards including DDR3 and GDDR series
• Integrated power good indication for system monitoring

Applications

• DDR3 memory termination circuits
• GDDR3/GDDR4/GDDR5 memory interface design
• High-speed bus termination control systems

Procurement Notes

Verify the specific suffix (e.g., TR) for tape-and-reel packaging requirements against your manufacturing needs. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the supplier provides original Microchip Technology documentation to validate authenticity and traceability for quality assurance purposes.

Selection Notes

Select this component when designing memory interfaces requiring dedicated dual regulation for termination voltages. It is suitable for applications needing support for DDR3 and various GDDR generations within a compact MSOP package. Consider the 15 mA supply current and 750 mV to 6 V input range during power budget calculations.

Part Context

This part belongs to Microchip's specialized PMIC family focused on memory power management. It serves as a dedicated controller rather than a standalone regulator, managing external components to achieve precise termination voltages. The MSOP-10 package allows for space-constrained designs in consumer electronics and computing hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts and control signals if considering alternative controllers from other manufacturers.
