Overview
The MIC2040-2YMM is a single-channel high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 0.8V to 5.5V and supports up to 500mA continuous output current with a programmable current limit set at 1.5A. The device features a maximum on-resistance of 75mΩ, ensuring efficient power delivery. Key protection mechanisms include thermal shutdown and short-circuit protection. The component is designed for surface mount installation in SOT-23 packages and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated soft-start circuitry minimizes inrush current for capacitive loads
- Programmable current limiting protects against overcurrent conditions
- Thermal shutdown safeguards the device and load from overheating
- Fault status flag provides detection for overcurrent and thermal events
Applications
- General purpose power distribution requiring circuit protection
- Multi-port USB applications satisfying upstream/downstream power requirements
- Low voltage switching systems needing high-side control
Procurement Notes
Verify the specific suffix '2YMM' against the official Microchip datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required operating voltage range of 0.8V to 5.5V. Confirm that the 75mΩ on-resistance meets system efficiency targets. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch is required for low-voltage applications. It is suitable for designs needing adjustable current limits and integrated fault reporting. Consider the 75mΩ on-resistance for power loss calculations. Verify that the SMD/SMT package style aligns with the PCB layout constraints and manufacturing capabilities.
Part Context
The MIC2040 series consists of single-channel low voltage power distribution switches optimized for general-purpose applications. These devices are designed to provide circuit protection through programmable current limiting and thermal shutdown. The family includes variants like the MIC2041 which offers auto-reset circuit breaker modes. They are commonly used in portable electronics and USB-powered devices.
Replacement Considerations
Consult the official Microchip datasheet for direct pin-to-pin replacements or functional equivalents within the MIC2040/2041 series. Verify that any substitute maintains the same voltage range, current handling capabilities, and protection features.
