What are the key features of PTPS23881RTQT?
- 8-channel IEEE 802.3bt high-power PoE PSE controller managing up to 8 PDs independently per device
- Integrated 200 mΩ RSENSE per channel eliminates external current-sense resistors, reducing BOM cost and board area
- Adjustable threshold detection with 3V to 3.6V logic supply enables flexible classification and current-limit tuning
- 56-pin QFN package introduced in 2019 for compact multi-port PoE switch and access-point designs
What is PTPS23881RTQT used for?
The PTPS23881RTQT is designed for multi-port PoE switches, wireless access points, and IP camera power systems where 8 independent channels must deliver IEEE 802.3bt-compliant power to connected devices. Its integrated 200 mΩ current-sense resistors per channel simplify PCB layout and reduce solution footprint in high-density enterprise networking equipment. The 3V to 3.6V supply voltage and adjustable threshold allow direct integration with modern 3.3V switch SoCs and flexible power budget allocation across ports.

Frequently Asked Questions
How many PoE ports can a single PTPS23881RTQT manage and what standard does it follow?
A single PTPS23881RTQT manages 8 independent PoE channels compliant with IEEE 802.3bt, allowing each port to independently classify, detect, and power PDs up to the high-power Type 3 or Type 4 budget from a 3V to 3.6V controller supply.
Why does the integrated 200 mΩ RSENSE matter for PoE switch PCB design?
The on-chip 200 mΩ RSENSE per channel eliminates 8 external current-sense resistors, reducing BOM component count, board space, and solder joint risk in a 56-pin QFN footprint, which is critical for compact 8-port access-point and switch designs.
What supply voltage does the PTPS23881RTQT require, and does it fit standard 3.3V system rails?
The PTPS23881RTQT requires a 3V to 3.6V supply voltage for its logic and control circuitry, which aligns directly with standard 3.3V system rails common in Ethernet switch SoCs and embedded networking platforms, avoiding separate regulator stages.
Which networking infrastructure applications benefit most from the PTPS23881RTQT's 8-channel architecture?
Multi-port PoE switches (8-port to 48-port with multiple ICs), enterprise wireless access points, IP surveillance camera hubs, and industrial Ethernet panels all benefit from 8 independently controlled channels, each with adjustable current thresholds and the 200 mΩ integrated sense resistor.
