MP6233DH-LF-Z

Overview

The MP6233DH-LF-Z is a dual-channel power distribution switch IC from Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports 3.3 V or 5 V systems. The device provides two independent outputs with a continuous output current of 1.5 A per channel. It features an active-high enable input, a maximum on-resistance of 130 mOhms, and a current limit of 2.3 A. The component includes soft-start timing of up to 3 ms and off-time delay of up to 10 ms. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in an MSOP-8 package.

Feature Summary

• Dual-channel power distribution with independent control via active-high inputs
• Integrated current limiting and overcurrent protection for load safety
• Controlled turn-on and turn-off timing to manage inrush currents

Applications

• Power distribution in portable electronic devices
• Peripheral power switching in consumer electronics
• Battery-powered equipment requiring efficient power management

Procurement Notes

Verify the specific suffix LF-Z indicates lead-free compliance and tape-and-reel packaging configuration as defined by the manufacturer. Confirm that the MSOP-8EP package dimensions match your PCB footprint requirements. Ensure the active-high logic level aligns with your system's control signals. Cross-reference the datasheet for thermal dissipation limits under your specific ambient conditions. Validate RoHS status through official manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when dual-channel power switching with moderate current capacity is required. The 1.5 A output current suits most low-power peripheral applications. The active-high enable simplifies interface with standard logic controllers. Consider the 130 mOhm on-resistance for efficiency calculations. The wide input voltage range allows compatibility with various battery states. Evaluate thermal performance if multiple channels operate simultaneously at high loads.

Part Context

This part belongs to the MPS power switch IC family designed for power distribution tasks. It complements other variants like the MP62341 series which offer different current ratings. The MP6233 specifically targets applications needing two switched rails with 1.5 A capability. It fits into the broader category of load switches used for sequence control and protection in mobile and industrial devices.
