Maxim MAX5982CETE+T

Контроллер (PD)70 W802.3at (PoE+), 802.3af (PoE)

Overview

The MAX5982CETE+ from Maxim Integrated Products is an IEEE 802.3af/at-compliant, powered device interface controller with integrated 70W high-power MOSFET in 16 pin TDFN package. It provides a complete interface for a powered device (PD) to comply with the IEEE® 802.3af/at standard in a power-over-Ethernet (PoE) system. It also provides PD with a detection signature, classification signature and an integrated isolation power switch with inrush current control. During the inrush period, The MAX5982CETE+ limit the current to less than 182mA before switching to the higher current limit (1700mA to 2100mA) when the isolation power MOSFET is fully enhanced. The device features an input UVLO with wide hysteresis and long deglitch time to compensate for twisted-pair cable resistive drop and to assure glitch-free transition during power-on/-off conditions. The MAX5982CETE+ can withstand up to 100V at the input.
