The TPS23841PAPR from Texas Instruments is a high-performance, quad-port Ethernet Power Sourcing Equipment (PSE) controller designed for Power over Ethernet applications. It supports IEEE 802.3af and 802.3at Type 1 standards, enabling power delivery up to 25W per port.
This controller operates over a wide input voltage range of 21.5V to 57V. Key features include integrated FETs, over-current reporting, over-temperature protection, and a high-speed 400-kHz I2C interface for comprehensive power management. It also offers controlled current ramp-up/down for EMI reduction and supports both AC/DC disconnect methods.
The TPS23841PAPR is available in a 64-pin HTQFP package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C, making it suitable for demanding industrial and enterprise environments.
Applications include high-power Ethernet enterprise switches, SOHO hubs, and mid-span PoE injectors. The integrated switches and sense resistors simplify system design.
