MIC5162BMM

Overview

The MIC5162BMM is a dual regulator controller designed for DDR3, GDDR3, GDDR4, and GDDR5 memory applications. It integrates two independent regulators to provide VDDQ and VTT termination voltages. The device features an enable pin for power management and includes short-circuit and over-temperature protection. It is housed in a 10-pin MSOP package.

Feature Summary

• Dual regulator controller architecture supporting DDR3 and high-speed bus termination
• Integrated short-circuit and over-temperature protection mechanisms
• Dedicated enable pin for controlled power sequencing

Applications

• DDR3 memory subsystems
• GDDR3/GDDR4/GDDR5 graphics memory interfaces
• High-speed bus termination circuits

Procurement Notes

Verify the manufacturer source carefully, as listings may attribute the part to AVLIS-CO or other distributors while the original design originates from Micrel/Microchip. Confirm the package type is MSOP-10L and check for RoHS compliance status. Ensure the specific suffix matches the required tape-and-reel or tube packaging configuration for your assembly line.

Selection Notes

Select this component when designing systems requiring synchronized VDDQ and VTT regulation for DDR3 or GDDR memory interfaces. It is suitable for applications needing JEDEC-compliant termination solutions with integrated protection features. Consider the 10-MSOP footprint constraints and thermal requirements during PCB layout planning.

Part Context

This component belongs to the Microchip (formerly Micrel) PMIC family specialized for memory power management. It serves as a dedicated controller for high-speed digital interfaces, replacing discrete resistor networks and separate regulator ICs to reduce board space and improve signal integrity in memory subsystem designs.
