Microchip Technology, Inc. PMIC - Hot Swap Controllers MIC2580A-1.0YTS-TR

The MIC2580A-1.0YTS-TR is a hot-swap controller designed for safe insertion and removal of PCI-based adapter cards in PCI hot-plug and CompactPCI systems. It manages four power supplies: +12V, +5V, +3.3V, and ,Äì12V, incorporating a circuit breaker function to protect against overcurrent conditions. The device features current foldback limiting to prevent large transient currents during card insertion and programmable slew-rate control to manage inrush currents for capacitive loads. Diagnostic outputs include "power good" (/PWRGD) and "overcurrent fault" (/FAULT) signals, both equipped with deglitch filters to minimize false triggers. The controller also includes integrated MOSFET switches for +12V and ,Äì12V, as well as high-side drivers for external switches managing +3.3V and +5V. 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 applications requiring reliable power management in hot-swap environments.
