MAX5952 High-Power, Quad, PSE Controller For Power-Over-Ethernet

The MAX5952 is a quad -48V power controller designed for use in IEEE 802.3af-compliant/pre-IEEE 802.3at-compatible power-sourcing equipment (PSE). This device provides powered device (PD) discovery, classification, current limit, DC and AC load disconnect detections in compliance with the IEEE 802.3af standard. The MAX5952 is pin compatible with MAX5945 LTC4258 LTC4259A PSE controllers and provides additional features.
The MAX5952 features high-power mode that provides up to 45W per port. The MAX5952 provides instantaneous readout of each port current through the IC Interface The MAX5952 also provides high-capacitance detection for legacy PDs.
The device features an IC-compatible, 3-wire ser 4f0 ial Interface and is fully software configurable and programmable. The class-overcurrent detection function enables system Power Management to detect if a PD draws more than the allowable current. The MAX5952 's extensive programmability enhances system flexibility, enables field diagnosis, and allows for uses in other applications.
The MAX5952 provides four operating modes to suit different system requirements. Auto mode allows the device to operate automatically without any software supervision. Semi-automatic mode automatically detects and classifies a device connected to a port after initial software activation, but does not power up that port until instructed to by software. Manual mode allows total software control of the device and is useful for system diagnostics. Shutdown mode terminates all activities and securely turns off power to the ports.
The MAX5952 provides input undervoltage lockout (UVLO), input undervoltage detection, a load-stability safety check during detection, input overvoltage lockout, overtemperature detection, output voltage slew-rate limit during startup, power-good status, and fault status. The MAX5952 's programmability includes start-up timeout, overcurrent timeout, and load-disconnect detect 4ef ion timeout.
The MAX5952 is available in a 36-pin SSOP package and is rated for both extended (-40C to +85C) and upper commercial (0C to +85C) temperature ranges.
