The MIC2585-2JYTS from Microchip Technology is a Dual-Channel Positive Voltage Hot Swap Controller that has been designed to facilitate the safe insertion of boards into live system backplanes. It requires an input voltage of 1.0 - 13.2 V. This e-Fuse IC has a programmable inrush current limiting function that uses few external discrete components and controls the gate of external N-channel MOSFETs, it limits the inrush current and provides output voltage slew rate control in harsh, critical power supply environments. It offers output turn-on sequencing and output tracking during turn-on and turn-off, making it a robust solution for many network applications that meet the power sequencing and protection requirements of multiple-voltage logic systems.
The hot swap controller includes an electronic circuit breaker with dual-level over-current fault sensing to eliminate false tripping, thereby providing a fast response to short-circuit conditions. It is also provided with over-voltage protection (OVP) and under-voltage lockout (UVLO) output monitoring, and fault status pin to prevent damage. This controller IC supports power-on reset and power-good status output indication functionalities for real-time status monitoring. It is available in a surface-mount package that measures 7.9 x 4.5 mm and is ideal for RAID systems, network servers, base stations, network switches, and hot-board insertion applications.
