Overview
The MIC2506BM-TR is a dual-channel high-side power distribution switch manufactured by Microchip Technology. It integrates two N-channel MOSFETs in an 8-SOIC package, designed for USB and general load switching applications. The device supports a load voltage range of 3V to 7.5V with a maximum output current of 1A per channel. Key electrical parameters include a typical on-resistance (Rds(on)) of 75mΩ and fixed current limiting protection. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates dual high-side N-channel switches for independent load control
- Provides comprehensive fault protection including fixed current limiting, over-temperature shutdown, and under-voltage lockout
- Features controlled slew rate to minimize inrush current and status flag output for diagnostic monitoring
Applications
- USB port power switching and protection
- Peripheral device power distribution
- Load switching in consumer electronics
Procurement Notes
Verify the specific suffix 'BM-TR' against the official Microchip datasheet to confirm pinout compatibility and tape-and-reel packaging specifications. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits. Cross-reference the 8-SOIC footprint dimensions during PCB layout finalization to guarantee mechanical fit and thermal performance requirements are met.
Selection Notes
Select this component when dual-channel high-side switching with integrated protection is required. The 75mΩ on-resistance offers low conduction losses for 1A loads. Consider the status flag feature if system diagnostics are necessary. Verify that the input signal levels are compatible with the non-inverting logic interface before integration into the design.
Part Context
This part belongs to the MIC2506 series of power distribution switches. It serves as a compact solution for managing multiple loads from a single power rail. The device replaces discrete MOSFET and protection circuit designs, reducing board space and component count while providing reliable overload protection in portable and industrial applications.
Replacement Considerations
Direct substitutes may include other dual-channel high-side switches from Microchip or Micrel with similar 1A ratings and SOIC-8 packages. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
