The Texas Instruments TPS23841PJD is an active, 4-channel PoE PSE controller designed for high-power Ethernet applications. It supports IEEE 802.3af and 802.3at Type 1 standards, offering a wide input voltage range from 21.5 V to 57 V. This controller features integrated FETs, over-current reporting, and over-temperature reporting for robust power management.
With support for 25 W power delivery per port, the TPS23841PJD is suitable for enterprise switches, SOHO hubs, and high-power mid-spans. It includes features like controlled current ramp-up/down for EMI reduction, DC disconnect detection, and a high-speed 400-kHz I2C interface. The device is available in a 64-HTQFP package with an exposed pad for enhanced thermal performance.
Key electrical specifications include an input voltage range of 21.5 V to 57 V, a typical current limit of 650 mA, and a current cutoff of 615 mA. The operating temperature range is from -40°C to 125°C. The controller integrates four channels, each capable of managing power sourcing for PoE-enabled devices.
