TPS2379DDAR Description

Short technical summary and product information.

The Texas Instruments TPS2379DDAR is an integrated circuit designed for implementing IEEE 802.3at Type 2 powered devices (PD). This 8-pin device integrates essential features such as detection, classification, and hardware classification, along with a 140-mA inrush current limit for safe startup.

 

Key electrical specifications include support for IEEE 802.3at Type 1 and Type 2 standards, with PD power levels of 13W, 25W, and greater than 25W. It operates with an input voltage range from 0V to 57V and features a minimum PoE current limit of 850mA. The typical inrush current limit is 0.14A, and the typical RDS(on) per FET is 420mΩ. The device offers DC/DC control for PD only.

 

Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount configuration, the TPS2379DDAR is rated for an operating temperature range of -40°C to 125°C (TJ). Its robust design includes thermal shutdown and fault response features, making it suitable for high-power PoE applications.

 

This controller is ideal for applications requiring efficient and reliable power delivery over Ethernet, such as IP phones, wireless access points, and security cameras.
