TPS2378DDA Description

Short technical summary and product information.

The Texas Instruments TPS2378DDA is an integrated circuit designed to implement an IEEE 802.3at Type-2 powered device (PD) interface. This controller supports both 802.3af (Type 1) and 802.3at (Type 2) PoE standards, enabling power delivery up to 25W.

 

Key electrical specifications include an input voltage range of 0V to 57V, a minimum PoE current limit of 850mA, and a typical inrush current limit of 0.14A. The device features a low 0.5-Ω hotswap MOSFET with a 100V rating, and an operating current up to 850mA with a typical operating current limit of 1A. It also includes features like PG, primary-side adapter priority, and thermal shutdown for robust operation.

 

The TPS2378DDA is housed in an 8-pin PowerSOIC package with PowerPAD technology for enhanced thermal dissipation. It is designed for surface mount applications and operates within an ambient temperature range of -40°C to 85°C. The device offers system-level ESD protection up to 15kV and 8kV.
