产品描述:
Single-Port, 40W, IEEE 802.3af/at PSE Controller with Integrated MOSFET40W, Single-Port, IEEE 802.3af/at-Compliant PSE Controller with Integrated 0.5Ω Power MOSFET and Sense Resistor
The MAX5971A is a single-port, power-sourcing equipment (PSE) power controller designed for use in IEEE® 802.3af/at-compliant PSE. This device provides powered device (PD) discovery, classification, current limit, DC and AC load-disconnect detections. The MAX5971A operates automatically without the need for any software programming and features an integrated power MOSFET and sense resistor. The device also supports new Class 5 and 2-event classification for detection and classification of high-power PDs. The MAX5971A provides up to 40W to a single port (Class 5 enabled) and still provides high-capacitance detection for legacy PDs.
The MAX5971A provides input undervoltage lockout (UVLO), input overvoltage lockout, overtemperature detection, output voltage slew-rate limit during startup, and LED status indication.
The MAX5971A is available in a space-saving, 28-pin TQFN (5mm x 5mm) power package, and is rated for the extended (-40°C to +85°C) temperature range.
