Overview
The MP62040DQFU-LF-Z is a single-channel power distribution switch manufactured by Monolithic Power Systems. It operates within an input voltage range of 1.7V to 5.5V and provides a continuous current limit of 2A. The device is housed in an ultra-small DQFU package, designed for space-constrained applications. It functions as a high-side switch with integrated current limiting protection.
Feature Summary
- Integrates a 2A current-limited power distribution switch for single-channel load management
- Operates across a wide supply voltage range from 1.7V to 5.5V
- Utilizes an ultra-small footprint package optimized for dense PCB layouts
Applications
- Portable electronic devices requiring compact power switching solutions
- Peripheral power distribution in consumer electronics
- Battery-powered equipment needing efficient load control
Procurement Notes
Verify the specific suffix LF-Z indicates lead-free compliance when sourcing. Confirm the DQFU package designation matches your board design requirements. Ensure the component meets RoHS standards for your target market regulations before finalizing procurement plans.
Selection Notes
Select this component when a single-channel high-side switch with 2A capacity is required. It is suitable for systems operating between 1.7V and 5.5V. Consider the ultra-small package size if board real estate is limited. Verify thermal performance under maximum load conditions for your specific application.
Part Context
This part belongs to the MP62040 series of power distribution switches from Monolithic Power Systems. The series includes variants such as the MP62040-1 which adds output discharge capabilities. The MP62040DQFU-LF-Z represents the standard current-limited version without active discharge features.
Replacement Considerations
The MP62040-1DQFU-LF-Z serves as a functional substitute if output discharge capability is required. Other MP62040 variants may be considered based on package or feature differences. Verify pin compatibility and electrical specifications before substituting.
