Power Over Ethernet (PoE) Controllers are devices used to provide power to Power over Ethernet (PoE) compliant electrical components and accessories. MAX5991BETP+T is a PoE Controller IC that provides the ability to regulate and distribute power over a Power over Ethernet cable. It is a highly efficient, reliable and secure method for power distribution over Ethernet networks. The MAX5991BETP+T is a single-phase, step-up, PoE Controller with an integrated, low-power, high-voltage (HV) MOSFET that is designed to meet IEEE 802.3bt Type 1 specifications.

The MAX5991BETP+T is designed to use the PoE cable as the source of power to supply power to any compliant device, like phones, modems, routers, and other peripherals. In addition, it is capable of accepting up to 39 watts of power, allowing it to support multiple Power-Productivity applications.

The MAX5991BETP+T is designed to provide excellent power efficiency while also providing protection against surges, spikes, overvoltage, and overcurrent. The device is equipped with an embedded microcontroller to ensure reliable power delivery, and its low-power sleep mode enables it to reduce power consumption when not in use. Additionally, it supports automatic regulation for efficient power conversion and distribution.

The MAX5991BETP+T is capable of both rectifying and converting incoming AC power from the PoE cable into a DC voltage which can then be used to power a target device. The integrated HV MOSFET within the device is used for rectifying and voltage selection. This MOSFET is used instead of a transformer as it is able to offer better efficiency and space savings. The device also supports power management features like overvoltage protection, overcurrent protection and forward current limiting.
