Overview
The MIC2525-1BM is an integrated high-side power switch optimized for Universal Serial Bus (USB) applications. It supports both self-powered and bus-powered configurations. The device features adjustable current limiting, over-temperature protection, and under-voltage lockout (UVLO). It operates with a single supply voltage and utilizes an SOIC-8 surface-mount package.
Feature Summary
- Integrated high-side power switching capability for USB interfaces
- Adjustable current limiting to protect downstream loads
- Built-in thermal shutdown and under-voltage lockout protections
Applications
- Self-powered USB host controllers
- Bus-powered USB peripheral devices
- USB port protection circuits
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm pinout and electrical characteristics. Note that this component is marked as not recommended for new designs; ensure compliance with current design guidelines before procurement.
Selection Notes
Select this component only for legacy maintenance or existing designs where the MIC2525 family is already established. Evaluate alternative modern USB power switches for new projects due to the manufacturer's recommendation against new design inclusion.
Part Context
The MIC2525 series belongs to Micrel's (now Microchip) portfolio of USB power control switches. The -1BM variant specifically denotes the SOIC-8 package version. This family was designed to manage power distribution in USB systems, providing essential protection features for host and peripheral connections.
Replacement Considerations
Consult Microchip's official obsolescence notices for approved replacement part numbers. Do not assume direct pin-to-pin compatibility with other USB switches without verifying datasheet specifications.
