MIC2003-0.5YML-TR

Power Distribution Switches, Load Drivers Overview

The MIC2003-0.5YML-TR is a single-channel P-channel power switch manufactured by Microchip Technology, designed for load distribution and protection applications. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum continuous output current of 500mA. The device features a typical on-resistance of 70 milliohms and utilizes a non-inverting open/switch interface. Integrated fault protections include fixed current limiting and overtemperature shutdown. It is housed in a compact 6-MLF (2x2mm) surface-mount package and functions across an ambient temperature range of -40°C to +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix YML-TR corresponds to the 6-MLF tape-and-reel packaging configuration. Confirm that the 500mA current rating aligns with the system's peak load requirements. Ensure the operating voltage range of 2.5V to 5.5V matches the target application's supply rails. Check for moisture sensitivity labeling if storage conditions are critical.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a compact, low-side or high-side P-channel switch is required for currents up to 500mA. It is suitable for applications needing integrated overcurrent and thermal protection without external sensing components. Consider the 70mΩ on-resistance for efficiency calculations. Ensure the non-inverting control logic compatibility fits the driving microcontroller or FPGA outputs.
