The Texas Instruments TPS2377DR-1 is an integrated circuit designed to function as a Power over Ethernet (PoE) Powered Device (PD) controller. It fully supports the IEEE 802.3af specification and is housed in an 8-pin SOIC package.
This controller features a wide input voltage range of 0V to 57V and can handle up to 13W of power. Key electrical specifications include a minimum PoE current limit of 405mA, a programmable inrush current limit, and a typical rDS(on) per FET of 580mΩ. It also includes an integrated 0.58-Ohm, 100-V low-side switch and offers overtemperature protection.
The TPS2377DR-1 operates within an industrial temperature range of -40°C to 85°C, making it suitable for various environmental conditions. It provides features such as programmable UVLO, open-drain power-good reporting, and auto-retry after current-limit faults. The device is designed for surface mount installation.
Applications for the TPS2377DR-1 include VoIP phones, WLAN access points, security cameras, internet appliances, and POS terminals that require PoE connectivity.
