Overview
The MIC2045-1BTS is a single-channel high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 0.8 V to 5.5 V and supports output currents from 1 A to 6 A. The device features a low on-resistance of 23 mΩ, facilitating efficient power delivery in low-voltage applications. It is housed in a 16-TSSOP package with a width of 4.40 mm. The component functions reliably across an operating temperature range of -40°C to +85°C. Designed for robust protection, it integrates current limiting and thermal shutdown capabilities to safeguard connected loads against fault conditions.
Feature Summary
- Single-channel high-side power switching architecture
- Integrated overcurrent and thermal protection mechanisms
- Low on-resistance design for efficient power distribution
- Wide input voltage compatibility for low-voltage systems
Applications
- Portable electronic devices requiring protected power rails
- Industrial control systems needing reliable load switching
- Consumer electronics with multiple peripheral connections
- Automotive infotainment and accessory power distribution
Procurement Notes
Verify the exact suffix matches your supply chain requirements. Confirm that the 16-TSSOP package dimensions align with your PCB footprint specifications. Ensure the operating temperature range meets your environmental constraints. Check for authenticity through authorized distributors only. Validate that the current rating suffices for your specific load application before finalizing procurement.
Selection Notes
Choose this component when a single high-side switch with integrated protection is required. Consider the 23 mΩ on-resistance for efficiency needs. Verify that the 0.8 V to 5.5 V input range covers your system voltage. Ensure the 16-TSSOP package fits your board layout. Evaluate if the 1 A to 6 A current capability matches your load demands. Compare against other channels if multiple switches are needed.
Part Context
This part belongs to the MIC2045 family of power distribution switches. It shares core protection features with variants like the MIC2045-2YTS but offers a single channel configuration. The family is designed for low-voltage applications requiring robust load management. Other members may differ in channel count or specific electrical thresholds while maintaining similar protective functionalities.
Replacement Considerations
Direct substitutes include MIC2045-1BTS-TR for tape-and-reel packaging. Variants like MIC2045-1YTS offer different suffix options. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same 16-TSSOP package and protection features.
