MP62170ES-1-LF-P

Overview

The MP62170ES-1-LF-P is a single-channel power switch IC from Monolithic Power Systems designed for distribution applications. It features an active-low output configuration with a maximum continuous output current of 1.5 A and a current limit threshold of 2.3 A. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes internal timing controls, specifying a maximum turn-on time of 3 ms and a maximum idle time of 10 ms. It exhibits a maximum on-resistance of 130 mΩ and supports operation across a temperature range of -20°C to +85°C.

Feature Summary

• Integrates active-low control logic for simplified interface with system controllers
• Provides built-in current limiting protection to safeguard downstream loads
• Features low on-resistance to minimize conduction losses in power distribution paths

Applications

• General-purpose power distribution units
• Load switching in embedded systems
• Peripheral power management circuits

Procurement Notes

Verify the specific suffix against official documentation, as the provided model references an 'LF-P' variant while primary records indicate 'LF-Z'. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors. Ensure the selected package matches the design requirements, as variations may exist between tape-and-reel and tube packaging options for this component family.

Selection Notes

Select this component for applications requiring a single high-side switch with moderate current capacity. Evaluate the 130 mΩ on-resistance against thermal constraints at full load. Consider the 2.7 V minimum operating voltage when designing for battery-powered systems. Verify that the 1.5 A output rating aligns with the connected load requirements and that the active-low control signal polarity matches the driving microcontroller or FPGA outputs.

Part Context

This part belongs to the MPS power switch IC portfolio, which focuses on integrated solutions for load distribution and protection. These devices typically combine MOSFET drivers with protection circuitry to replace discrete transistor designs. The series aims to reduce board space and simplify design implementation by integrating timing and current limit functions into a compact surface-mount package.
