Overview
The MP5090GQHT-Z is a high-efficiency dual load switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 500 mV to 5.5 V and supports two independent outputs with a continuous output current of 3 A per channel. The device features a maximum on-resistance of 20 mOhms and includes programmable soft-start and discharge functions. It is housed in an 8-pin TQFN package, suitable for surface mount applications across a temperature range of -40°C to +125°C.
Feature Summary
- Dual-channel architecture providing independent control over two power paths
- Integrated output discharge function for rapid capacitor discharge upon shutdown
- Programmable soft-start capability to limit inrush current during power-up
Applications
- Portable consumer electronics requiring efficient power distribution
- Embedded systems needing controlled power sequencing
- Battery-powered devices utilizing low-voltage operation
Procurement Notes
Verify the specific suffix HT-Z indicates tape and reel packaging when ordering. Confirm the operating voltage requirements align with the 500 mV to 5.5 V specification. Ensure thermal management strategies account for the TQFN-8 package characteristics under maximum load conditions. Cross-reference the datasheet for exact pinout configurations to prevent layout errors.
Selection Notes
Select this component for designs requiring dual isolated power rails with low on-resistance. Consider the 20 mOhm typical resistance for efficiency calculations. Evaluate the need for programmable soft-start against system inrush current constraints. Compare against single-channel alternatives if only one output is required to optimize board space.
Part Context
This part belongs to the MPS MP5090 series of load switches. It shares family features such as low IQ and high efficiency but differs from variants like the MP5092 which offer higher current ratings. The GQHT-Z designation specifies the lead-free, halogen-free status and the specific reel packaging format for automated assembly.
Replacement Considerations
Direct substitutes include other MPS dual load switches with similar electrical parameters. Verify compatibility regarding package dimensions and pin assignments before replacing. Check if alternative parts meet the same -40°C to +125°C operating temperature range.
