MP5090GQHT-P

Overview

The MP5090GQHT-P is a dual-channel load switch from Monolithic Power Systems, designed for high-efficiency power distribution. It operates within a supply voltage range of 0.5V to 5.5V and delivers a continuous output current of 3A per channel. The device features a maximum on-resistance of 20mΩ and includes programmable current limiting set at 3.6A. Key timing parameters include a maximum turn-on time of 2ms and a maximum idle time of 90ms. It supports an operating temperature range from -40°C to +125°C and is housed in a TQFN-8 surface-mount package.

Feature Summary

• Dual-channel architecture providing independent control over two separate power rails
• Low on-resistance design to minimize conduction losses and improve thermal performance
• Integrated current limiting protection to safeguard downstream loads from overcurrent conditions
• Programmable soft-start and idle timer functions to manage inrush current and system sequencing

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Industrial equipment needing robust load switching with overcurrent protection
• Consumer electronics utilizing low-voltage power distribution networks
• Embedded systems requiring controlled power-up sequences and fault isolation

Procurement Notes

Verify the specific suffix P indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TQFN-8 footprint matches your PCB layout requirements. Cross-reference the datasheet for exact thermal dissipation limits under your specific ambient conditions. Validate that the 3A continuous current rating meets your peak load demands without exceeding thermal constraints.

Selection Notes

Select this component when dual-channel switching with moderate current capacity is required. The 20mΩ on-resistance offers a balance between efficiency and cost for 3A applications. Consider the 2ms turn-on time for systems sensitive to inrush currents. The wide input voltage range accommodates various battery and rail configurations. Evaluate the TQFN-8 package size against available board space constraints.
