概述

Description

LTC4263CDE-1#PBF is Analog Devices’ IEEE 802.3af/at PoE PD controller. It provides the PoE-powered-device (PD) interface—handling detection, classification, and power-path control—and feeds a downstream DC–DC converter with a protected high-side path. The device accepts the PoE input (up to the typical PSE rail voltages used by PoE, e.g., up to ~57 V), offers current limiting and fault protection, and is designed to simplify PoE PD designs with integrated power-path control and protections (OC/UV/OT, thermal, etc.). The "CDE-1" suffix denotes a specific Pb-free, RoHS-compliant package variant, while "#PBF" confirms Pb-free packaging. This part is commonly used in PoE-powered devices such as IP cameras, VoIP phones, wireless access points, and other networked endpoints.
Note: For exact pinout, electrical characteristics, timing, and recommended application circuits, consult the LTC4263 datasheet and product page.

Features

Here are the typical features of the LTC4263CDE-1#PBF family (hot-swap/power-path controller):
- Hot-swap controller with integrated high-side switch for power-path control
- Inrush/current-limit protection with soft-start
- Programmable current limit for protection against short-circuits
- Reverse-current protection and load-disconnect behavior
- Overvoltage and undervoltage protection on the input/output
- Thermal protection/shutdown
- Overcurrent protection with fault latch and auto-retry behavior
- Enable/disable control and automatic recovery
- Fault/status signaling outputs (fault and status indicators)
- Wide input voltage range suitable for automotive/industrial applications
- Low quiescent current in steady state
- Pb-free package (CDE-1 variant, PBF)
Note: For exact electrical specs (limits, timing, pinout), refer to the LTC4263CDE-1#PBF datasheet.

Package

8‑lead MSOP (Mini Small Outline Package), 3x3 mm, plastic. PBF indicates RoHS-compliant, lead-free.

Pinout

- Pin count: 16 pins
- Function: LTC4263CDE-1#PBF is a hot‑swap controller with high‑side MOSFET drive, providing current‑limit and soft‑start/inrush control plus protection (overcurrent/short‑circuit, undervoltage/overvoltage) to protect a board when plugged into a live backplane. It drives an external N‑MOSFET and offers fault indication.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LTC4263CDE-1#PBF is a Linear Technology part that is now sold under Analog Devices after their acquisition of Linear Technology.
- What kind of company: Analog Devices is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits, including power management and signal-conditioning devices.

Application

- PoE PD front-end controller for IEEE 802.3af/at
- PoE-powered devices: IP cameras, VoIP phones, wireless access points
- Remote sensors and industrial IoT equipment
- LED lighting and signage powered over Ethernet
- PoE-enabled point-of-sale terminals and similar distributed equipment
