Overview
The MIC2005-0.5LYM5-TR is a single-channel, high-side power distribution switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET topology to manage load power within a voltage range of 2.5V to 5.5V. The device supports a maximum output current of 500mA and features a typical on-resistance of 70mΩ. It includes fixed current limiting protection and over-temperature shutdown for fault management. The component operates with an inverting input interface and is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained applications.
Feature Summary
- Integrates a high-side P-channel power switch for general-purpose load control
- Provides fixed current limiting and thermal shutdown for circuit protection
- Features an inverting logic interface for straightforward drive compatibility
Applications
- General-purpose power distribution in embedded systems
- Load switching for peripheral devices in consumer electronics
- Battery-powered equipment requiring efficient power management
Procurement Notes
Verify the specific suffix 'LYM5' against the official Microchip datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental constraints. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a high-side switch with integrated protection is required for low-voltage loads up to 500mA. The inverting input simplifies control logic compared to non-inverting alternatives. Consider the 70mΩ on-resistance for power loss calculations. Compare against the MIC2005A series if non-inverting input or different current limits are needed. Ensure the SOT-23-5 package fits the PCB layout constraints.
Part Context
This part belongs to the MIC2005 family of fixed and adjustable current-limiting power switches. It is designed as a cost-effective solution for protecting loads from overcurrent and thermal faults. The family offers various configurations including different current limits and input types. This specific variant uses a P-channel device for high-side switching applications.
Replacement Considerations
Check the MIC2005A-2YM5-TR for a non-inverting alternative. Verify pin-to-pin compatibility before substitution. Review datasheets for differences in Rds(on) and current limit thresholds.
