The MIC2587-2BM from Microchip Technology is a robust, high-performance single-channel power ORing controller designed to enhance system reliability in redundant power supply systems. This component is a critical piece of the power management puzzle, particularly suitable for servers, telecom, data centers, and industrial applications where uninterrupted power is crucial.

Key Features

• Single-Channel ORing Controller: The MIC2587-2BM is designed to control a single external N-Channel MOSFET in power ORing applications.
• Wide Operating Voltage Range: This device can handle a broad range of input voltages from 1.35V to 13.2V, making it versatile for various system voltage requirements.
• Fast Turn-Off Fault Response: It offers a quick response to fault conditions, ensuring rapid disconnection of the faulty power source to prevent damage to the system.
• Reverse Current Blocking: The controller provides reverse current blocking capability, which prevents current from flowing backward through the power supply during a fault or shutdown state.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the ORing controller operates only when the voltage is within the specified range, safeguarding the system from low voltage anomalies.
• Charge Pump Drive: The integrated charge pump circuitry efficiently drives the gate of the external N-Channel MOSFET above the source voltage to ensure low on-resistance and minimal voltage drop across the switch.
• Thermal Shutdown Protection: The MIC2587-2BM includes thermal shutdown protection to prevent overheating, enhancing the longevity and reliability of the device.

Applications

The MIC2587-2BM is ideal for systems that require high reliability in power sourcing, such as:

• Redundant power supplies
• Servers and network routers
• Telecommunications equipment
• Industrial control systems
• Data storage systems

With its combination of performance, protection features, and versatility, the MIC2587-2BM is a top choice for designers looking to enhance their power management strategies in critical systems.
