MIC2564A-1YSM-TR

Overview

The MIC2564A-1YSM-TR is a high-side power switch IC manufactured by Microchip Technology, designed for PCMCIA and CardBus applications. It features an N-channel output configuration with a 3:4 input-to-output ratio, supporting up to four independent switches. The device operates within a voltage range of 3.3V, 5V, and 12V loads and provides a maximum output current of 120mA per channel. It includes fixed current limiting and overtemperature fault protection mechanisms. The component is housed in a 24-SSOP package (0.209" width) and functions across a temperature range of -40°C to +85°C.

Feature Summary

High-side power switching with N-channel output configuration
Integrated fixed current limiting and overtemperature protection
Status flag reporting capability for fault monitoring

Applications

PCMCIA card slot power management
CardBus interface power distribution
Low-voltage load driver circuits

Procurement Notes

This component is officially classified as Not Recommended for New Designs (NRND) or End-of-Life by the manufacturer. Verify availability through authorized distributors and confirm that alternative part numbers are suitable for your specific design requirements before procurement.

Selection Notes

Select this IC for legacy systems requiring 3:4 control logic mapping for multiple power channels. Ensure the application supports the 24-SSOP surface mount package and operates within the specified -40°C to +85°C ambient temperature range. Confirm compatibility with 3.3V, 5V, and 12V load voltages.

Part Context

The MIC2564A series belongs to Microchip's family of power distribution switches and load drivers. This specific variant integrates control logic for managing multiple high-side switches from fewer input lines, simplifying system architecture for portable electronic devices and expansion card interfaces.
