Product Overview
The MAX5922AEUI+T is a +48V, single port network power switch for power over LAN in 28 pin TSSOP package. Designed for power sourcing equipment in power over LAN applications and is fully compliant to IEEE 802.3af standard. It provides power devices (PD) discovery, classification, current limit and other necessary functions for an IEEE 802.3af compliant PSE. In midspan mode, detection collision avoidance circuit provides the necessary back-off timing to prevent fault detections that happen when two different PSEs try to detect and power same PD. After successfully discovering and classifying a PD it enters start-up mode. During start-up, it limits the output voltage and current slew rate to minimize EMI. Typical applications include power-sourcing equipment (PSE), power-over-LAN/power-over-MDI, computer telephony, single port power and midspan power injector, switches/routers with in-line power.
- 32V to +60V wide operating input range, 1mA analogue input supply current
- Operating temperature range from -40°C to 85°C, programmable UVLO and is set to 38V internally
- 0.45ohm integrated power switch, 100μA PD leakage detection tolerant
- Selectable detection collision avoidance
- Programmable current limit, zero current detection with status output
- Input logic signals compatible with 1.8V to 5V CMOS logic
- Separate analogue and digital grounds with up to ±4V offset
- Overcurrent and overtemperature protection with status outputs
- Current limit foldback with timeout and duty cycle control
- Latch or autorestart fault management
