Microchip MIC2587R-1YM

Overview

The MIC2587R-1YM and MIC2587R are single-channel positive voltage hot swap controllers designed to provide safe insertion and removal of boards for systems that require live (always-powered) backplanes. These devices use few external components and act as controllers for external N-channel power MOSFET devices to provide inrush current control and output voltage slew rate control. Overcurrent fault protection is provided via programmable analog foldback current limit circuitry equipped with a programmable overcurrent filter. These protection circuits combine to limit the power dissipation of the external MOSFET to insure that the MOSFET is in its SOA during fault conditions. The MIC2587R-1YM provides a circuit breaker function that latches the output MOSFET off if the load current exceeds the current limit threshold for the duration of the programmable timer. The MIC2587R provides a circuit breaker function that automatically attempts to restart power after a load current fault at a low duty cycle to prevent the MOSFET from overheating. Each device provides either an active-HIGH (-1BM) or an active-LOW (-2BM) "Power-is-Good" signal to indicate that the output load voltage is within tolerance.
