Description
MIC2777-25YM5-TR is Microchip’s MIC2777 hot-swap controller in the YM5 package (Tape & Reel). It protects a live power rail by actively driving an external N‑channel MOSFET to limit inrush current during plug-in and rail transients.
Key points
- Adjustable current limit via an external resistor
- Soft-start to reduce inrush
- Protection: overcurrent/short‑circuit, undervoltage lockout, and open-load detection
- Fault/status output for MCU monitoring
Typical uses
- Server, telecom, and other hot‑swap power rails
- Disk drives, backplanes, and other plug-in modules
Packaging/ordering
- YM5 package; -TR indicates Tape & Reel
Note
- Refer to the MIC2777 datasheet for exact electrical specs, pinout, and resistor calculations.
