Microchip | MIC2584-JYTS

The MIC2584-JYTS is a dual-channel positive voltage hot swap controller designed to facilitate the safe insertion of boards into live system backplane. The MIC2584-JYTS is available in 16-pin and 24-pin TSSOP packages, respectively. Using a few external discrete components and by controlling the gate drives of external N-Channel MOSFET devices.

The MIC2584/85 provides inrush current limiting and output voltage slew rate control in harsh, critical power supply environments. Additionally, the MIC2585 provides output turn-on sequencing and output tracking during turn-on and turn-off. In combination, the devices’ many features provide a simplified, robust solution for many network applications to meet the power sequencing and protection requirements of multiple-voltage logic systems.

Key Features:

• 1.0 V to 13.2 V supply voltage operation.
• Surge voltage protection up to 20 V.
• Current regulation limits inrush current regardless of load capacitance.
• Programmable inrush current limiting.
• Electronic circuit breaker.
• Dual-level overcurrent fault sensing eliminates false tripping.
• Fast response to short circuit conditions (< 1 µs).
• Two sequenced output mode selections. (MIC2585 only).
• D250mV supply tracking mode during turn-on/turn-off (MIC2585 only).
• Overvoltage and undervoltage output monitoring (Overvoltage for MIC2585 only).
