LTC4259ACGW General Description

The LTC4259ACGW is a Power over Ethernet (PoE) controller designed for use in Power Sourcing Equipment (PSE) applications. It is manufactured by Analog Devices Inc. and is offered in a 24-lead SSOP package. This device is compliant with the IEEE 802.3af standard and is capable of delivering up to 25.5W of power to an Ethernet-powered device. The LTC4259ACGW features built-in classification circuitry that allows it to identify and communicate with powered devices, as well as provide necessary power in a safe and efficient manner.Key features of the LTC4259ACGW include a programmable current limit, inrush current limiting, and a hot swap controller which ensures safe insertion and removal of powered devices. It also provides protection against overcurrent, overvoltage, and short-circuit events.The device operates over a wide input voltage range of 35V to 57V and has a quiescent current of only 600μA, making it suitable for low power applications. It also offers a variety of configurable options through its I2C interface, allowing for customization based on specific requirements.
