MIC2085 Single-Channel Low Voltage Hot Swap Controller
●General Description
▲The MIC2085 is a single channel, positive voltage, hot swap controller designed to allow the safe insertion of boards into live system backplanes. The MIC2085 is available in a 16-pin QSOP package. Using a few external components and by controlling the gate drive of an external N-Channel MOSFET device, the MIC2085 provides inrush current limiting and output voltage slew rate control in harsh, critical power supply environments. Additionally, a circuit breaker function will latch the output MOSFET off if the current limit threshold is exceeded for a programmed period of time. The device’s array of features provide a simplified yet robust solution for many network applications in meeting the power supply regulation requirements and affords protection of critical downstream devices and components
