Visão Geral

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.

Equivalent

MIC2777-25YM5-TR is a 2.5 V voltage supervisor/reset (push-pull output). Common equivalents (2.5-V threshold) from major vendors:
- TI: TPS3800/TPS383x family
- Microchip: MCP13x/MCP12x (2.5-V variants)
- Maxim: MAX809/MAX810 (2.5-V options)
- Onsemi: NCS/NCP series 2.5-V reset supervisors
- ST: STM803/STM805 family (2.5-V)

Features

Here are the typical features of the MIC2777-25YM5-TR (MIC2777 family), variant details may vary—please check the datasheet for exact numbers:
- Fixed output option (2.5 V for the -25 variant)
- Enable/control input to turn the regulator on/off
- Low dropout/high efficiency regulator
- Overcurrent/short-circuit protection
- Thermal shutdown protection
- Reverse-current protection
- Stable with ceramic capacitors
- Small package with Tape & Reel (YM5/TR) packaging
Note: Exact specifications (input range, max load current, accuracy, dropout, quiescent current) depend on the specific variant; confirm with the datasheet for precise figures.

Pinout

- Pin count: 8 pins (8‑pin package).
- Function: High‑side hot‑swap controller with current limiting and protection (inrush limiting, overcurrent/overvoltage/short‑circuit protection) that drives an external MOSFET to protect a live power path; includes enable and fault/status signaling.

Manufacturer

Manufacturer: Microchip Technology Inc. It is a global semiconductor company that designs, manufactures, and sells microcontrollers, analog products, memory, and other integrated circuits for embedded systems and electronics applications.

Application

Application areas:
- Hot‑swap and power‑path protection for backplanes and multi‑card systems
- High‑side load switching with current limiting in telecom, networking, automotive, and industrial equipment
- Power management and sequencing for battery‑powered portable devices
- LED lighting/backlight drivers requiring controlled current and fault protection
- General DC rail protection in consumer electronics
These reflect typical uses of MIC2777‑25YM5‑TR as a high‑side switch/power‑path protection device.

Package

The MIC2777-25YM5-TR is in a 5-pin SOT-23 package (SOT-23-5), delivered in Tape & Reel (TR).
