Maxim Integrated MAX5984AETI T
- Part Number:
- MAX5984AETI T
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3267174-MAX5984AETI T
- Description:
- IC CTRLR PD IEEE W/MOSFT 28TQFN
- Datasheet:
- MAX5984AETI T
Description
The MAX5984 is a single-port power-sourcing equipment (PSE) power controller designed for use in IEEE® 802.3af/at-compliant PSE. It provides powered device (PD) discovery, classification, current limit, and DC and AC load-disconnect detections. The MAX5984 operates automatically without the need for any software programming and features an integrated power MOSFET and sense resistor. It also supports new Class 5 and 2-Event classification for detection and classification of high-power PDs. The MAX5984 provides up to 40W to a single port (Class 5 enabled) and still provides high-capacitance detection for legacy PDs.
Features
IEEE 802.3af/at Compliant
Up to 40W for Single-Port PSE Applications
Integrated 0.52 Power MOSFET and Sense Resistor
2-Event Pin-Select (MAX5984A/MAX5984B)
PD Detection and Classification
Programmable Current Limit for Class 5 PDs
High-Capacitance Detection for Legacy Devices
Supports Both DC and AC Load Removal Detections
Current Foldback and Duty Cycle-Controlled Current Limit
LED Indicator for Port Status
Direct Fast-Shutdown Control Capability
Space-Saving, 28-Pin TQFN (5mm x 5mm) Package
Applications
Single-Port PSE End-Point Applications
Single-Port PSE Power Injectors (Midspan Applications)
PoE Repeaters
Switches/Routers
Industrial Automation Equipment
Wireless LAN Access Point/WiMAX Base Stations
