概述

Description

MIC2777-25YM5-TR is a Microchip/Micrel MIC2777 family high-side switch (hot-swap controller) with built-in overcurrent protection. It limits inrush current when a load is connected to a live rail and protects the circuit from short circuits via current limit, plus undervoltage lockout and thermal shutdown. The “-25” denotes a fixed current‑limit variant (typical around 2.5 A; confirm exact value in the datasheet). The device controls a power MOSFET to switch the rail on/off, with a controlled startup to minimize transients. YM5 is the package code and TR indicates Tape & Reel packaging for automated assembly. Common uses include hot‑swap protection on power rails, backplanes, server/telecom boards, and other systems requiring safe power-up. For exact electrical specs, pinout, timing, and packaging details, consult the MIC2777 datasheet and packaging guide.

Features

Key features of MIC2777-25YM5-TR (Micrel/Microchip voltage supervisor):
- Fixed 2.5 V reset threshold
- Wide operating supply: approx 2.7 V to 5.5 V
- Reset output: active-low, CMOS push-pull
- Internal power-on reset with deterministic reset pulse
- Very low quiescent current (microamp range)
- Fast response to supply dips, ensuring reliable MCU resets
- Temperature range typical: -40°C to +125°C
- Package: YM5 (5-pin SOT-23) with Tape & Reel (TR)
- No external components required; RoHS-compliant
Application areas: microcontroller and processor resets, battery-powered and power-fail monitoring.

Package

It uses a 5-pin SOT-23 package (SOT-23-5), shipped in Tape & Reel (TR).

Pinout

Pin count: 5 pins (SC-70/5-pin package; YM5 code; TR = Tape & Reel).
Function: Fixed 2.5V low-dropout regulator (LDO).

Manufacturer

- Manufacturer: Microchip Technology (Micrel, Inc. lineage; MIC2777 was from Micrel and Microchip acquired Micrel in 2015).
- What kind of company: A global semiconductor company that designs, develops, manufactures, and sells integrated circuits (embedded microcontrollers, analog/mixed-signal ICs, memory, interfaces, etc.) for embedded systems.

Application

Applications: hot-swap protection and inrush current limiting for DC rails in servers, telecom and industrial equipment; power-path control and ORing for redundant power supplies; supply sequencing and protection for microprocessor-based boards; protection of sensitive loads from fault conditions (overcurrent/short-circuit) in data centers and networking gear.
