Overview
The MP62180DD-LF-Z is a single-channel power distribution switch IC from Monolithic Power Systems, designed for 3.3V and 5V systems. It features an active-low enable input and delivers a continuous output current of 2A with a 2.8A current limit. The device operates within a supply voltage range of 2.7V to 5.5V and includes a maximum on-resistance of 130mΩ. Timing characteristics specify a maximum turn-on time of 10ms and a maximum turn-off time of 3ms. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a 2A current-limited power switch with low on-resistance for efficient power distribution.
- Features an active-low control interface for straightforward logic-level integration.
- Provides built-in timing controls with defined turn-on and turn-off delays.
Applications
- Power distribution in 3.3V and 5V embedded systems
- Load switching for peripheral devices
- Overcurrent protection in portable electronics
Procurement Notes
Verify the specific suffix LF-Z against official MPS documentation to confirm lead-free compliance and package details. Confirm the active-low enable configuration matches system requirements. Check the NRND status with the manufacturer for long-term availability assurance before finalizing design implementation.
Selection Notes
Select this component when a single-channel switch with a 2A continuous rating and active-low control is required. Ensure the 130mΩ on-resistance meets thermal constraints for the target load. Verify that the 2.7V to 5.5V supply range aligns with the system's available power rails and logic levels.
Part Context
This part belongs to the MP62180 series of power distribution switches. It is distinct from the MP62181, which utilizes an active-high enable input. Both share similar electrical ratings but differ in control polarity. The DD-LF-Z designation indicates a QFN-8 surface-mount package with lead-free termination.
Replacement Considerations
The MP62180DS-LF-Z is a parameter-equivalent alternative within the same family, differing primarily in the enable signal polarity (active-high vs. active-low). Designers must verify logic level compatibility when substituting between these variants.
