MIC2562A-1YTS

Overview

The MIC2562A-1YTS is a power distribution switch and load driver manufactured by Microchip Technology. It features a 3:2 input-to-output ratio with two N-channel outputs configured for low-side switching. The device supports load voltages of 3.3V, 5V, and 12V, delivering a maximum output current of 200mA per channel. It operates within a temperature range of -40°C to +85°C and is housed in a 16-TSSOP package. Key electrical characteristics include a typical on-resistance of 70 milliohms and non-inverted logic inputs.

Feature Summary

• Integrates an internal charge pump to facilitate efficient power switching without external supply requirements.
• Provides comprehensive fault protection mechanisms including fixed overcurrent limiting and thermal shutdown capabilities.
• Includes status flag outputs to indicate operational state and fault conditions for system monitoring.

Applications

• PCMCIA socket power control
• CardBus interface power management
• General-purpose load driving for low-voltage digital systems
