MIC2562A-1BTS-TR

Overview

The MIC2562A-1BTS-TR is a dual N-channel power switch IC designed for PCMCIA and CardBus socket applications. It features two independent outputs capable of sourcing up to 200mA each. The device supports load voltages of 3.3V, 5V, and 12V. It utilizes logic-level inputs for control and operates in a low-side output configuration. The component is housed in a 16-pin TSSOP package.

Feature Summary

• Dual N-channel power switching capability for independent circuit control
• Integrated protection mechanisms for socket power management
• Logic-compatible interface for direct system processor connection

Applications

• PCMCIA socket power controllers
• CardBus socket power distribution
• Portable computer peripheral power management

Procurement Notes

Verify the specific suffix '1BTS' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and compliance with RoHS standards. Cross-reference the part number with the latest Microchip Technology documentation to avoid discrepancies in revision levels or packaging specifications.

Selection Notes

Select this component when designing systems requiring isolated power switching for multiple PCMCIA or CardBus slots. The dual-output architecture simplifies board layout by integrating control logic and protection circuits into a single package. Consider the 200mA current limit per channel when sizing traces and ensuring thermal performance within the TSSOP enclosure meets the application's operational temperature range.

Part Context

This part belongs to the MIC2562A family of power distribution controllers. Variants such as MIC2562A-0YM and MIC2562A-1YM share similar functional architectures but may differ in input configurations or internal protection thresholds. The MIC2562A series is specifically engineered for mobile computing environments where space constraints and power efficiency are critical design factors for peripheral connectivity.

Replacement Considerations

Direct substitutes include other MIC2562A variants like MIC2562A-1YM if pin compatibility is verified. Generic replacements require careful evaluation of voltage ratings and current limits to ensure equivalent performance in PCMCIA/CardBus applications without altering the system's power management behavior.
