Microchip Technology, Inc. Hot Swap Controllers MIC2580A-1.6BTS

The MIC2580A-1.6BTS is a hot-swap controller designed for safe insertion and removal of PCI-based adapter cards in PCI hot-plug and CompactPCI systems. It supports four power supplies: +12V, +5V, +3.3V, and ,Äì12V, and features a circuit breaker function to protect against overcurrent conditions. The device includes programmable slew-rate control to limit inrush currents and current foldback limiting to prevent large transient currents during card insertion. Diagnostic outputs for voltage supervision include "power good" (/PWRGD) and "overcurrent fault" (/FAULT), both equipped with deglitch filters to minimize nuisance tripping. The controller also integrates high-side drivers for external MOSFETs and provides a precharge supply for CompactPCI I/O terminations. The operating temperature range is from -40°C to +85°C, and it comes in a 24-lead TSSOP package. This product is suitable for engineers looking for reliable hot-swap solutions in their PCI or CompactPCI applications.
