Overview
The MIC2045-1YTS-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a low on-resistance of 21 mOhm and supports an input voltage range from 0.8V to 5.5V. The device provides overcurrent protection with a current limit adjustable between 1A and 6A. It operates within a temperature range of -40°C to +85°C and is housed in a 16-TSSOP surface-mount package.
Feature Summary
- Integrated high-side MOSFET switch for general-purpose power distribution
- Built-in fault protection including overcurrent limiting and thermal shutdown
- Slew rate controlled turn-on to minimize inrush current
- Status flag output indicating power good or fault conditions
Applications
- General-purpose power distribution systems
- Circuit protection in embedded electronics
- Load switching in consumer devices
- Industrial control power management
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the exact current limit setting required, as the MIC2045 series allows adjustment between 1A and 6A depending on the variant. Ensure the application voltage stays within the 0.8V to 5.5V operational range. Check datasheet for precise thermal dissipation requirements in the 16-TSSOP package.
Selection Notes
Select this component for applications requiring robust high-side switching with integrated protection. The wide voltage range suits both 3.3V and 5V systems. Consider the 21 mOhm on-resistance for efficiency needs. Verify if the status flag interface is compatible with the host controller. Compare against similar parts like the MIC2044 if dual-channel functionality is not needed.
Part Context
The MIC2045 belongs to a family of high-side MOSFET switches designed for circuit protection. It complements the single-channel MIC2044 and multi-channel variants. The device integrates control logic with a power MOSFET to simplify design. It is optimized for reliability in harsh environments with extended temperature ratings.
Replacement Considerations
Direct substitutes include other Microchip high-side switches like the MIC2044 for single-channel needs. Cross-reference pinouts and electrical parameters carefully. Ensure replacement parts support the same voltage and current limits. Verify package compatibility for PCB layout reuse.
