The MAX5971AETI+T (MAX5971A) is a power converter for PoE applications with integrated Ethernet jack protection and a wide input voltage range. It is a type of PMIC - Power Over Ethernet (PoE) Controller. As part of a PoE system, the MAX5971A is used to regulate the power delivered to Ethernet network devices.
The basic operating principle of the MAX5971A is simple: it uses an integrated power audio transformer to draw energy from a power source, such as a wall outlet or battery, and then regulates this energy so that the correct amount of power is delivered to the Ethernet device. This power regulation process is accomplished by the MAX5971A\'s onboard voltage regulation circuit.
The MAX5971A is designed to efficiently convert power from a wide range of sources, such as an AC wall outlet or a DC battery. It can operate over a wide input voltage range (18V to 55V). The MAX5971A also incorporates two Ethernet jack protection circuits that protect against overvoltage and overcurrent conditions.
The MAX5971A is suitable for a wide range of PoE applications requiring efficient, low-noise power conversion, such as Wired Ethernet and Wi-Fi applications, connected home gateways, residential gateways, Set Top Boxes (STBs), network cameras, VoIP phones, IP phones and other Ethernet based devices. In addition, the MAX5971A is designed to meet the latest IEEE 802.3af/at or IEEE 802.3bt power standards.
The MAX5971AETI+T includes features such as input voltage leakage and over-temperature protection, power sequencing, output over-current protection, output voltage regulation and adjustable current limiting. The device also includes a thermal shutdown stage for added protection against thermal events caused by power surges or overloads.
In summary, the MAX5971AETI+T is a PoE power converter with integrated Ethernet jack protection and a wide input voltage range. It is designed to meet the latest IEEE 802.3af/at or IEEE 802.3bt power standards, and is suitable for a range of PoE applications requiring efficient, low-noise power conversion.
