Introduction
The LTC4296-1 is an IEEE 802.3cg-compliant, five port, single-pair power over Ethernet (SPoE), power sourcing equipment (PSE) controller. SPoE simplifies system design and installation with standardized power and Ethernet data over a single-pair cable. The LTC4296-1 is designed for interoperability with 802.3cg powered devices (PDs) in 24 V or 54 V systems. The LTC4296-1 delivers power using external, low drain-to-source on resistance (RDS(ON)), N-channel metal-oxide semiconductor field-effect transistors (MOSFETs), which minimize voltage drop and ensure application ruggedness.
High-side circuit breakers with foldback, analog current limit (ACL) provide controlled inrush and short-circuit protection. An optional low-side circuit breaker protects the negative output against backfeed faults, and ground faults in nonisolated applications. PD classification via the serial communication classification protocol (SCCP) and maintain full voltage signature (MFVS) ensure full operating voltage is only applied to the cable when a PD is present. The SWx pins disconnect port power snubbers during detection and classification. PD initiated sleep and wake-up are supported. The WAKEUP pin supports wake-up forwarding. Telemetry, status, and software control features are accessed via a serial peripheral interface (SPI) bus interface with packet error code (PEC) protection.
The LTC4296-1 provides a versatile SPoE, PSE solution for 10BASE-T1L controllers and switches and can easily be integrated with the Analog Devices, 10BASE-T1L transceiver portfolio, such as the ADIN1100 (physical layer, PHY), ADIN1110 (MACPHY), and ADIN2111 (2-port switch).
