MP62550DGT-LF-Z

Overview

The MP62550DGT-LF-Z is a single-channel low-side power distribution switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.5 V to 5.5 V and supports an output current up to 1.5 A. The device features an adjustable current limit ranging from 60 mA to 1.7 A, with a maximum on-time of 3 ms and idle time of 30 ms. It includes over-temperature protection and under-voltage lockout (UVLO). The component is housed in a TQFN-6 package with an exposed pad and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates adjustable current limiting functionality for precise load protection
• Includes built-in thermal shutdown and under-voltage lockout mechanisms
• Configurable timing parameters for controlled turn-on and off cycles

Applications

• Peripheral power switching in portable electronic devices
• Load management in automotive infotainment systems
• Power distribution in industrial control modules

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.

Selection Notes

Select this component when a single-channel low-side switch with adjustable current limiting is required. Ensure the application voltage does not exceed 5.5 V and that the load current remains within the 1.5 A continuous rating. Consider the TQFN-6 package size and thermal dissipation capabilities relative to the PCB layout constraints.

Part Context
