Overview
The MIC2003-0.8YM5-TR is a high-side power distribution switch manufactured by Microchip Technology, housed in an SOT-23-5 surface-mount package. It utilizes a P-channel MOSFET architecture to manage loads within a voltage range of 2.5V to 5.5V. The device supports a continuous output current of 800mA with a typical on-resistance of 70 milliohms. Integrated protection mechanisms include fixed current limiting and thermal shutdown. It operates reliably across a temperature range of -40°C to +85°C.
Feature Summary
- High-side switching capability using a P-channel MOSFET for efficient load control
- Integrated fixed current limiting and thermal shutdown for robust fault protection
- Low on-resistance design minimizes power dissipation during conduction
Applications
- Portable electronic devices requiring compact power management
- Peripheral circuit protection in consumer electronics
- Battery-powered systems needing efficient load switching
Procurement Notes
Verify the specific suffix YM5 corresponds to the SOT-23-5 tape and reel packaging configuration required for your assembly line. Confirm that the 800mA current rating aligns with your maximum load requirements. Ensure the operating voltage range of 2.5V to 5.5V matches your system supply rails. Check for any recent product change notices regarding manufacturing sites or material composition updates.
Selection Notes
Select this component when a compact high-side switch with integrated protection is needed. The P-channel topology simplifies drive logic compared to N-channel alternatives. Consider the 70 milliohm on-resistance for thermal management calculations. Verify that the SOT-23-5 footprint fits your PCB layout constraints. Evaluate if the fixed current limit meets your short-circuit protection needs without external components.
Part Context
This part belongs to the MIC2003 family of single-channel power switches. It shares the same functional block diagram as other variants but differs in current handling capabilities and package options. The family is designed for general-purpose power distribution applications where space and integration are critical factors.
Replacement Considerations
Direct substitutes include MIC2003-0.5YM5-TR for lower current applications or MIC2004-0.8YM5-TR for similar performance in different configurations. Verify pin compatibility and electrical specifications before substitution.
