MAX5986AETE+, Power Over Ethernet (POE) Controller, IEEE 802.3af, Class-1 -2, 60V In, 35.7V UVLO, 215kHz, TQFN-16

Semiconductors - ICs\Power Management ICs - PMIC\Power-over-Ethernet - POE Controllers The MAX5986AETE+ is an IEEE 802.3af-compliant, high-efficiency, Class 1/Class 2, PDs with integrated DC to DC converter in 16 pin TQFN package. It provides a complete power-supply solution as IEEE® 802.3af-compliant Class 1/Class 2 powered devices in a Power over Ethernet system. The device integrates the PD interface with an efficient DC to DC converter, offering a low external part count PD solution. The MAX5986A include sleep and ultra-low power modes. The PD interface provides a detection signature and a Class 1/Class 2 classification signature with a single external resistor. The PD interface also provides an isolation power MOSFET, a 60mA (max) inrush current limit and a 323mA operating current limit. The integrated step down DC-DC converter uses a peak current-mode control scheme and provides an easy-to implement architecture with a fast transient response. It operates at a fixed 215KHz switching frequency. • Wide input voltage range from 8.7V to 60V • Protects against overload, output short circuit, output overvoltage and overtemperature • Integrated TVS diode withstands cable discharge event (CDE) • PoE class 1/class 2 classification set with single resistor • Intelligent maintain power signature (MPS) complies with IEEE 802.3af specification • Simplified wall adapter interface • Pass 2KV, 200m CAT-6 cable discharge event • Sleep and ultra low power mode • Frequency foldback for high-efficiency light-load operation, Back-bias to optimize efficiency • Hiccup-mode runaway current limit, 49mA (typ) inrush current limit
