MIC2545A-1BTS

Overview

The MIC2545A-1BTS is a high-side power switch IC featuring an N-channel output configured for single-channel distribution. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 3A. The device incorporates a typical on-resistance of 35 milliohms and provides programmable current limiting adjustable between 500mA and 3A. Designed for surface-mount installation in a 14-TSSOP package, it functions across an operating temperature range of -40°C to +85°C.

Feature Summary

Integrated high-side switching with N-channel output configuration
Programmable current limit protection ranging from 500mA to 3A
Controlled slew rate functionality to minimize inrush currents
Built-in status flag output for fault monitoring

Applications

USB power distribution networks
DC power switching systems
General power management applications requiring high-side control

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified partners. Confirm the specific suffix '1BTS' corresponds to the 14-TSSOP package variant. Check for RoHS compliance status as indicated in official documentation, noting potential variations in environmental certifications for legacy stock.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required for low-voltage DC applications. Ensure the load voltage does not exceed 5.5V and that the thermal requirements fit within the -40°C to +85°C operational range. Verify that the 14-TSSOP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the MIC2545A family of integrated high-side power switches optimized for low-loss DC power switching. The series is designed to provide robust protection features including overcurrent, overtemperature, and reverse current blocking capabilities for sensitive downstream loads.
