MIC2025-2YMM-TR: A 1.2A Single-Channel Power Distribution Switch

In the realm of modern electronic design, efficient and reliable power management is paramount. The MIC2025-2YMM-TR stands out as a highly integrated, single-channel power distribution switch designed to provide robust control and protection for downstream circuitry. This device is engineered to handle loads up to 1.2A, making it an ideal solution for a wide array of applications, including USB ports, peripherals, and other low-voltage systems requiring precise power switching.

A key feature of the MIC2025-2YMM-TR is its ultra-low on-resistance (Rₒₙ), which typically measures just 85mΩ. This low resistance is critical as it minimizes the voltage drop and power loss across the switch, thereby enhancing overall system efficiency and thermal performance. Designers can achieve higher efficiency and reduced heat dissipation, which is especially valuable in space-constrained and battery-powered devices.

The IC incorporates comprehensive protection features to safeguard both the host system and the connected load. It includes integrated thermal shutdown that deactivates the switch if the junction temperature exceeds safe limits, preventing damage from overheating. Furthermore, the built-in current limiting circuit protects against short circuits and excessive inrush currents, which can be detrimental to system integrity. An under-voltage lockout (UVLO) feature also ensures the device remains off until the input voltage reaches a stable, sufficient level, guaranteeing proper operation during power-up sequences.

Control is facilitated through a simple logic-compatible enable pin, allowing the switch to be toggled via a microcontroller or system logic. The fast turn-on time ensures the load is powered quickly, meeting the demands of high-speed digital systems. The device is offered in a compact, space-saving 8-pin μMAX package, making it suitable for portable and densely populated PCB designs.

ICGOOODFIND: The MIC2025-2YMM-TR is a robust and efficient power distribution switch that combines low power dissipation, comprehensive protection, and a small form factor. It is an excellent choice for designers seeking to improve power management reliability in consumer electronics, computer peripherals, and portable devices.
