MP5090GC-Z

Overview

The MP5090GC-Z is a high-efficiency, dual-channel load switch manufactured by Monolithic Power Systems. It operates within an input voltage range of 0.5V to 5.5V and supports a continuous output current of 2A per channel. The device features a maximum on-resistance of 30 mOhms and includes current limiting set at 3.6A. Key timing parameters include a maximum turn-on time of 2 ms and a maximum turn-off time of 90 ms. It is housed in an 8-ball CSP package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel configuration for independent power distribution control
• Low on-resistance design for high efficiency and minimal voltage drop
• Integrated current limiting to protect against overload conditions
• Controlled slew rate management to reduce inrush current

Applications

• Portable electronic devices requiring efficient power management
• Embedded systems with multiple voltage rails
• Battery-powered equipment needing low quiescent current operation
• Industrial control modules operating in harsh environments

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when ordering. Confirm the CSP-8 package type matches your PCB footprint requirements. Ensure the 2A per channel rating aligns with your load specifications. Check for any specific tape and reel quantities if using automated assembly lines. Validate that the 0.5V minimum operating voltage suits your system's power rail.

Selection Notes

Select this component when dual-channel isolation is required within a compact form factor. The low 30 mOhm resistance makes it suitable for applications prioritizing power efficiency. Consider the 2A current limit for moderate load scenarios. The wide input voltage range accommodates various battery types. Ensure thermal management is adequate for the expected ambient temperatures up to 125°C.

Part Context

This part belongs to the MP5090 series of load switches from Monolithic Power Systems. It is designed for space-constrained applications where multiple power switches are needed. The series emphasizes high efficiency and low standby current. It serves as a solution for managing power distribution in modern portable electronics and embedded systems.

Replacement Considerations

Direct substitutes may include other dual-channel load switches from MPS with similar current ratings. Verify pin compatibility and package dimensions before substitution. Ensure equivalent electrical characteristics such as on-resistance and current limits are met.
