Overview
The MP62351ES-LF-P is a dual-channel high-side power distribution switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.7V to 5.5V and supports loads up to 500mA per channel. The device features an active-high interface for control. Key electrical parameters include a maximum on-resistance of 85mΩ, a current limit of 650mA, a maximum turn-on time of 3ms, and a maximum foldback time of 10ms. It functions across an operating temperature range from -20°C to +85°C and is housed in an SOIC-8 surface-mount package.
Feature Summary
- Dual-channel high-side switching capability for independent load control
- Integrated current limiting protection with foldback functionality
- Active-high logic interface for straightforward system integration
Applications
- Peripheral power distribution in portable electronic devices
- Load switching in USB hub architectures
- Power management in industrial control modules
Procurement Notes
Verify the specific suffix (LF-P) against official Monolithic Power Systems documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the SOIC-8 footprint matches your PCB design guidelines. Cross-reference the datasheet revision date to validate thermal and electrical specifications before finalizing procurement orders.
Selection Notes
Select this component when dual-channel high-side switching is required within a 5.5V system. It is suitable for applications needing moderate current handling up to 500mA with integrated overcurrent protection. Consider the 85mΩ on-resistance for efficiency calculations and ensure the active-high control logic aligns with the host microcontroller or system controller outputs.
Part Context
This part belongs to the MPS power distribution switch family designed for low-voltage applications. It provides reliable load switching with built-in protection mechanisms. The dual-channel configuration allows for efficient space utilization in compact designs compared to using single-channel alternatives.
Replacement Considerations
Consult official MPS substitution guides for verified equivalents. Generic replacements may differ in on-resistance, current limits, or package dimensions. Verify compatibility with existing control logic and thermal requirements before substituting.
