The MIC2085 and MIC2086 are single-channel positive designs that allow safe voltage hot-swap controllers for live system boards to be plugged into the backplane. The MIC2085 and MIC2086 are available in 16-pin and 20-pin QSOP packages. Using few external components and by controlling external N-channel gate drive MOSFET devices, the MIC2085/86 provide inrush current limiting and output voltage slew rate control in harsh, critical power supply environments. Additionally, the circuit breaker will lock the output MOSFET for the programmed time if the current limit function exceeds the threshold. "The functional array of devices provides a simplified yet robust conference power that many network application solutions supply with regulatory requirements and provide protection for critical downstream equipment and components.
