MIC2045-1BTS-TR

Overview

The MIC2045-1BTS-TR is a high-side power distribution switch manufactured by Microchip Technology. It features an N-channel MOSFET configured for 1:1 load driving within a 16-TSSOP package. The device supports an input voltage range of 0.8 V to 5.5 V and operates with a supply voltage (Vcc/VDD) between 1.6 V and 5.5 V. Key electrical specifications include a typical on-resistance (Rds On) of 20 mOhm and a maximum output current of 6 A. The component integrates non-inverting input logic, slew rate control, and status flagging capabilities.

Feature Summary

• Integrates power good indication and status flag outputs for system monitoring
• Features controlled slew rates to minimize inrush current during turn-on
• Provides high-side switching capability with low on-resistance for efficient power delivery

Applications

• Power distribution networks in embedded systems
• Load driver circuits for peripheral devices
• Hot-swap applications requiring controlled turn-on characteristics

Procurement Notes

Verify the complete part number including the -TR suffix to confirm tape-and-reel packaging configuration. Ensure compatibility with the required 16-TSSOP footprint and pinout dimensions. Cross-reference the manufacturer datasheet for specific thermal performance data under intended operating conditions. Confirm that the supply voltage range aligns with the system's power architecture before integration.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection and status signaling is required. The 6 A current rating and 20 mOhm on-resistance suit moderate-power loads. Consider the 1.6 V minimum Vcc requirement for logic compatibility. The non-inverting input simplifies control interface design compared to active-low alternatives.

Part Context

This part belongs to the MIC2045 series of power switches from Microchip Technology. It is designed as a robust solution for managing power delivery to downstream components. The 16-TSSOP package provides a compact form factor suitable for space-constrained printed circuit board layouts while maintaining adequate thermal dissipation for its current capabilities.
