MIC2583-LBQS-TR

Hot Swap Controllers Overview

The MIC2583-LBQS-TR is a single-channel positive voltage hot swap controller manufactured by Microchip Technology. Designed for safe board insertion into live system backplanes, it controls the gate drive of an external N-Channel MOSFET to manage inrush current and output voltage slew rate. The device operates within a supply voltage range of 2.3V to 13.2V and draws a typical supply current of 1.5 mA. It features programmable fault timeout, UVLO, and slew rate settings. The component is housed in a 16-pin QSOP package and supports an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides controlled inrush current limiting and output voltage slew rate management via external N-Channel MOSFET gate drive.
• Includes circuit breaker functionality that latches the output MOSFET off when current limit thresholds are exceeded for a set duration.
• Offers programmable parameters including fault timeout, undervoltage lockout (UVLO), and slew rate for flexible system integration.

Hot Swap Controllers Applications

• Safe insertion of boards into live system backplanes
• Harsh power supply environments requiring inrush current control
• Critical power supply applications with circuit breaker requirements

Hot Swap Controllers Procurement Notes

Verify the specific suffix LBQS against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the required 16-pin QSOP footprint and check for any recent Product Change Notices regarding packaging or testing sites. Confirm RoHS compliance status matches project requirements before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this controller for single-channel applications requiring precise control over power-up sequences and fault protection. It is suitable where external MOSFETs are preferred for handling higher currents or voltages than integrated switches allow. Consider the programmable features for customizing protection thresholds and timing characteristics to match specific system constraints.

Hot Swap Controllers Part Context

This component belongs to the MIC2582/MIC2583 family of single-channel hot swap controllers. While the MIC2582 utilizes an 8-pin SOIC package, the MIC2583 variant uses a 16-pin QSOP package, offering additional pinouts for enhanced programmability and feature access. Both devices share similar core functionalities for managing hot insertion events in electronic systems.
