LTC4296AUK-1#PBF

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. It is designed for interoperability with 802.3cg powered devices (PDs) in 24V or 54V systems. It 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. PD classification via the serial communication classification protocol (SCCP) and maintain full voltage signature (MFVS) ensure that the full operating voltage is only applied to the cable when a PD is present. Typical applications are operational technology (OT) systems, building and factory automation systems, field instruments and switches, security systems, traffic control systems.

• Adjustable source and return electronic circuit breakers
• Charge pump enhances the external, high-side, N-channel MOSFETs
• Supports SCCP with external microcontroller, SPI bus interface with PEC
• Voltage, current, and temperature telemetry, per port power-good comparators
• PD sleep, wake-up, and wake-up forwarding support
• Input supply operating range from 6 to 60V
• Input supply current is 6.5mA typical (all ports in power-on state)
• 48-lead plastic QFN package
• Temperature rating range from -40°C to +125°C
