TPS2383APMR

Overview

The TPS2383APMR is an eight-channel Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3af standards. It operates within a supply voltage range of 3V to 3.6V for logic and 44V to 57V for power stages, drawing a typical supply current of 5mA. The device supports a maximum power output of 15.4W per channel and functions reliably across an operating temperature range of 0°C to 70°C. Packaged in a 64-LQFP (10x10mm) surface-mount enclosure, it integrates classification and management features without internal switches.

Feature Summary

• Supports eight independent PoE channels compliant with IEEE 802.3af standards
• Integrates classification and management logic for centralized control
• Operates on dual voltage supplies for logic and power domains
• Designed for high-density Power Sourcing Equipment applications

Applications

• High-port-count Power Sourcing Equipment (PSE) systems
• Centralized PoE management units
• Industrial networking infrastructure controllers

Procurement Notes

Verify component status as the TPS2383 series may be obsolete or end-of-life depending on the specific suffix and manufacturer updates. Confirm RoHS compliance and moisture sensitivity level requirements for your assembly process. Ensure compatibility with existing PCB footprints for the 64-LQFP package. Review latest datasheets for any design-in warnings or recommended alternative components due to discontinuation.

Selection Notes

Select this controller for designs requiring centralized management of multiple PoE ports under the 802.3af standard. It is suitable for applications needing external switch integration rather than integrated solutions. Consider thermal management capabilities given the 15.4W per channel support. Evaluate system architecture needs for separate logic and power supply rails before implementation.

Part Context

The TPS2383 family consists of multi-channel PSE controllers designed to simplify the implementation of IEEE 802.3af compliant networks. These devices allow designers to build cost-effective, high-density PoE injectors and switches by offloading classification and management tasks from the main processor. The PMG4 and APMR variants share core functionality but differ in packaging and commercial specifications.

Replacement Considerations
