MP5990GMA-0000-Z

Hot Swap Controllers Overview

The MP5990GMA-0000-Z is a fully integrated hot-swap voltage controller from Monolithic Power Systems. It supports input voltages from 4V to 16V and handles up to 50A continuous current with a 1mΩ RDS(ON) internal switch. The device features a PMBus interface for configuration and monitoring, including programmable current limits up to 100A. It operates within a temperature range of -40°C to +125°C in an LGA-45 package.

Hot Swap Controllers Feature Summary

• Fully integrated hot-swap solution with built-in power MOSFET
• PMBus interface for digital control and system management
• Programmable current limiting and soft-start capabilities
• Comprehensive protection against over-current and thermal faults

Hot Swap Controllers Applications

• Server backplane power distribution
• Telecommunications equipment power modules
• Industrial control system hot-plug interfaces
• Network infrastructure power supplies

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per MPS standards. Confirm the LGA-45 package dimensions match your PCB footprint requirements. Ensure PMBus compatibility with your host controller's I2C protocol implementation. Check moisture sensitivity level handling procedures during assembly.

Hot Swap Controllers Selection Notes

Select this component when high-current hot-swap functionality with digital control is required. The 1mΩ switch minimizes conduction losses compared to discrete solutions. The PMBus interface allows for dynamic adjustment of protection thresholds. Consider the LGA-45 package size relative to available board space.

Hot Swap Controllers Part Context

Part of the MP5990 series designed for high-power density applications. Integrates control logic and power stage into a single compact package. Targets systems requiring reliable hot-plug insertion without power supply disruption. Complements other MPS PMICs for complete power management architectures.

Hot Swap Controllers Replacement Considerations

MP5991GLU-P/Z offers similar 16V/50A specifications with identical pinout and functionality. Verify PMBus command set compatibility between MP5990 and MP5991 variants before substitution. Both devices share the same LGA-45 package form factor for direct replacement.
