TPS23754PWPR PoE PD controller 1 Channel 802.3at (PoE+), 802.3af (PoE)
The TPS23754PWPR is a highly integrated, IEEE 802.3bt-compliant Power over Ethernet (PoE) powered device (PD) controller from Texas Instruments. This advanced chip is designed to support high-power PoE applications, delivering up to 90W of power with its robust architecture. It features an integrated 100V, 0.4Ω N-channel MOSFET, which enhances efficiency and reduces external component count, making it ideal for space-constrained designs. The TPS23754PWPR supports both alternative A and B powering schemes, ensuring compatibility with a wide range of PoE switches and midspan injectors. Its advanced detection and classification mechanisms comply with IEEE 802.3af/at/bt standards, providing reliable power negotiation and management.
The device incorporates multiple protection features, including thermal shutdown, inrush current limiting, and undervoltage lockout (UVLO), ensuring safe operation under various conditions. Its wide input voltage range (2.7V to 57V) allows flexibility in different PoE environments. Additionally, the TPS23754PWPR supports autonomous operation, reducing the need for external microcontroller intervention, which simplifies system design. The chip is available in a compact HTSSOP-20 (PWP) package, optimized for high-power density applications such as IP cameras, wireless access points, and industrial IoT devices.
For applications requiring lower power or different feature sets, alternative PD controllers include the TPS23861 (supports 8-pin configuration with advanced diagnostics), LTC4267 (high-efficiency, 4-pair PoE support), and MAX5969B (integrated DC-DC controller with wide input range). These alternatives provide varying levels of integration and power-handling capabilities to suit different design requirements.
