MP62340DS-LF-P

Overview

The MP62340DS-LF-P is a dual-channel low-side power distribution switch from Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and provides two independent outputs with a continuous output current of 1 A per channel. The device features a maximum on-resistance of 130 mOhms and includes a fixed current limit of 1.5 A for protection. Key timing parameters include a maximum turn-on time of 3 ms and a maximum idle time of 10 ms. It is housed in an SOIC-8 surface-mount package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent control over two separate load paths
• Integrated active-low enable logic for straightforward interface with digital controllers
• Built-in fault protection mechanisms including thermal shutdown and over-current limiting

Applications

• Power distribution networks requiring isolated switching for multiple loads
• Industrial control systems managing peripheral devices
• Embedded electronics needing reliable low-side switching capabilities

Procurement Notes

Verify the specific suffix LF-P against official MPS documentation to confirm lead-free compliance and tape-and-reel packaging specifications. Ensure that the active-low control requirement aligns with your system's logic levels. Cross-reference the SOIC-8 footprint dimensions with your PCB layout guidelines to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when dual-channel low-side switching is required within a 5.5 V maximum system voltage. Consider the 130 mOhms on-resistance for efficiency calculations and the 1.5 A current limit for overload protection needs. Evaluate the thermal performance at the expected operating temperature range to ensure reliability under continuous load conditions without exceeding junction limits.

Part Context

This part belongs to the MP62340 series of power distribution switches designed for efficient load management. It complements other MPS offerings by providing a cost-effective solution for multi-channel applications. The series focuses on integrating protection features into a compact form factor, supporting various industrial and consumer electronic designs that demand robust power routing.

FAQ

What is the control logic type for the enable pins?

The MP62340DS-LF-P utilizes active-low logic, meaning the channels are enabled when the input signal is driven low.

How does the device handle over-temperature conditions?

The IC incorporates thermal shutdown protection that automatically disables the output if the junction temperature exceeds safe operating limits.
