MP5496GR-0001-P

Overview

The MP5496GR-0001-P is a specialized PMIC from Monolithic Power Systems operating within a 2.8V to 5.5V input range. It integrates four synchronous buck converters with output currents of 4.5A, 2.5A, 4A, and 2A, alongside five LDOs. The device features a 1.5MHz switching frequency and supports flexible system settings via I2C and OTP. It operates between -40°C and +125°C in a QFN-28 package.

Feature Summary

• Integrates four high-efficiency synchronous buck DC/DC converters and five low-dropout linear regulators for comprehensive power management.
• Enables flexible system configuration through an I2C interface and One-Time Programmable (OTP) memory for preset parameters.
• Includes built-in protection mechanisms such as undervoltage lockout, overcurrent protection, and thermal shutdown.
• Supports programmable power sequencing and control logic via OTP or I2C bus interfaces.

Applications

• Portable electronic devices requiring multi-rail power distribution
• Industrial equipment utilizing single-supply architectures
• Embedded systems needing integrated voltage regulation and sequencing

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout compatibility and functional equivalence. Ensure the ordering code matches the required packaging format and temperature grade. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution is needed for multiple voltage rails from a single input source. The integrated nature reduces external component count compared to discrete regulator designs. Consider the I2C and OTP capabilities if dynamic adjustment or factory-programmed settings are required for production efficiency.

Part Context

This part belongs to the MP5496 series of professional power management ICs designed for space-constrained applications. It consolidates multiple power stages into a single QFN-28 package, replacing several individual regulators. The series emphasizes high integration and flexible configuration options for modern embedded systems.

Replacement Considerations

MP5496GR-0001-Z serves as a verified alternative within the same series, offering identical electrical characteristics and functionality. Verify that any substitute maintains the same QFN-28 footprint and pin assignment to ensure direct board compatibility without schematic modifications.
