Microchip Technology's MIC2587R-2YM Product Overview

The MIC2587R-2YM is a high-performance, single-channel power ORing controller developed by Microchip Technology. Designed to enhance system reliability, this device offers an efficient solution for power distribution systems that require multiple power sources, commonly found in redundant power systems of telecom and server applications.

Featuring a 2.5V to 14V operating range, the MIC2587R-2YM caters to a broad spectrum of power rails, making it a versatile choice for various applications. Its integrated MOSFET control circuitry ensures seamless switching between power sources, minimizing the risk of system downtime due to power failure.

With its proprietary active current limiting, the MIC2587R-2YM provides accurate overcurrent protection that can be programmed via an external resistor. This active management of the current ensures that the power system operates within safe limits, protecting both the ORing controller and downstream components.

The device's low quiescent current, typically 75µA, contributes to its high efficiency, making it an ideal choice for power-sensitive applications. In addition, the MIC2587R-2YM features a fast turn-off transient response, which is critical for protecting the system during sudden overcurrent events.

For enhanced system monitoring and control, the MIC2587R-2YM incorporates a fault status output that signals any detected issues, such as overcurrent or overtemperature conditions. This allows for immediate system response, further improving the reliability and robustness of the power system.

The MIC2587R-2YM comes in a compact 8-pin SOIC package, offering a space-saving solution without compromising performance. Its lead-free and RoHS-compliant design aligns with modern environmental standards, making it a responsible choice for eco-conscious designs.

In summary, the MIC2587R-2YM from Microchip Technology is a feature-rich power ORing controller that offers superior performance and reliability for systems that cannot afford power interruption. Its advanced protection features, low power consumption, and compact form factor make it an excellent choice for designers looking to enhance their power distribution systems.
