LTC4259ACGW-1 General Description

The LTC4259ACGW-1 is a power sourcing equipment (PSE) controller designed for use in Power over Ethernet (PoE) applications. It features an integrated powered device (PD) interface and supports IEEE 802.3af-compliant PDs. The controller can provide up to 45W of power, making it suitable for a wide range of PoE devices.This controller includes a programmable current limit, which allows for customization based on the specific requirements of the connected PD. It also features a built-in thermal shutdown protection mechanism to prevent overheating and ensure safe operation.The LTC4259ACGW-1 operates with a wide input voltage range of 36V to 57V, making it compatible with a variety of power sources. It also includes a power-good indicator for monitoring the status of the power supply. The controller is housed in a compact 36-lead SSOP package, making it easy to integrate into PoE systems.
