Texas Instruments TPS23880 | Demoboard TPS23880EVM: PoE, PSE, TPS23880 Evaluation Module
IEEE 802.3bt 8-Channel Power-over-Ethernet (PoE) PSE With Programmable SRAM
Overview
| Topology | Other Topology |
| IC revision | A |
Description
The TPS23880 is an 8-channel power sourcing equipment (PSE) controller engineered to insert power onto Ethernet cables in accordance with the IEEE 802.3bt (draft) standard. The eight individual power channels can be configured in any combination of 2-Pair (1-channel) or 4-Pair (2-channels) PoE Ports. The PSE controller can detect powered devices (PDs) that have a valid signature, determine the power requirements of the devices according to their classification, and apply power.
Features
- IEEE 802.bt (Draft) PSE Solution for Type 3 or Type 4 PoE Applications
- Eight Independent PSE Channels
- SRAM Programmable Memory
- Selectable 2-Pair or 4-Pair Port Power Allocations– 15.4 W, 30 W, 45 W, 60 W, 75 W, or 90 W
- Single and Dual Signature PD Compatibility
- Dedicated 14-BitCurrent A2Ds Per Port– Inherent Filtering– 2% Current Sensing Accuracy– 100-ms Rolling Port Current Averaging– Noise Immune MPS for DC Disconnect
- 1- and 3-Bit Fast Port Shutdown Input
- “Never Fooled” 4-Point Detection
- Programmable Power Limiting Accuracy +/- 3%
- Inrush and Operational Foldback Protection
- 425-mA and 1.25-A Selectable Current Limit
- Port Re-Mapping
- Auto-Class Discovery and Power Measurement
- 8-Bit or 16-Bit 1 MHz I2C Communication
- Flexible Processor Controlled Operating Modes– Auto, Semi Auto, and Manual / Diagnostic
- Per Port Voltage Monitoring and Telemetry
- –40°C to +125°C Temperature Operation
Typical applications
- Connected Ceiling LED Lighting Switches
- Network Video Recorders (NVRs) / Wireless Backhaul and Small Cell Networking / Enterprise and SoHO Switches and Routers
- PoE Pass-Through Power Modules
