Overview
The MP62170EK-1-LF-P is a single-channel power distribution switch IC manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1.5 A with a fixed current limit of 2.3 A. The device features a maximum on-resistance of 130 mΩ, a maximum turn-on time of 3 ms, and a maximum dwell time of 10 ms. It functions with active-low control signals and is rated for operation between -20°C and +85°C.
Feature Summary
- Integrates high-side load switching capability with built-in overcurrent protection mechanisms.
- Provides precise current limiting to safeguard downstream loads from fault conditions.
- Features low on-resistance to minimize conduction losses and heat generation during operation.
Applications
- Peripheral power distribution in portable electronic devices
- Load switching for USB-powered accessories
- Power management in industrial control systems
Procurement Notes
Verify the specific suffix 'P' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free characteristics as stated in the datasheet. Ensure the component is suitable for new designs, noting that related variants may carry different lifecycle statuses such as NRND.
Selection Notes
Select this component when a single-channel high-side switch with 1.5 A continuous current capability is required. Ensure the system voltage remains within the 2.7 V to 5.5 V operating range. Consider the 130 mΩ on-resistance for thermal management calculations. Verify that the active-low control logic aligns with the system's microcontroller or GPIO outputs.
Part Context
This part belongs to the MP62170 series of power switches from Monolithic Power Systems. These components are designed for efficient power distribution in compact applications. The EK suffix typically indicates an MSOP-8 package variant. Related models like the MP62171EK offer similar functionality with potential differences in pinout or specific electrical characteristics.
FAQ
What is the control logic level for turning the switch on?
The MP62170EK-1-LF-P utilizes an active-low control signal to enable the output.
Does the device include reverse current protection?
Official datasheets for the MP62170 series typically specify fixed current limiting and thermal shutdown, but reverse current protection is not explicitly confirmed for this specific part number without direct datasheet verification.
