TPS2419DR Description

Short technical summary and product information.

The TPS2419DR from Texas Instruments is an N+1 ORing controller IC, designed to enhance power supply reliability in systems requiring high availability. This device facilitates the ORing of multiple power sources, ensuring continuous operation even if one source fails.

Key electrical specifications include an input voltage range of 0.8V to 16.5V and a maximum output current capability of 250A. The controller operates with a typical quiescent current of 1.2mA and a maximum of 7mA. It features gate drive capabilities with source and sink currents, and a pulsed gate current rating of 2.35A. The operating temperature range is specified from -40°C to 85°C, suitable for industrial applications.

The TPS2419DR utilizes an external N-channel MOSFET for power switching. It offers features such as gate ON/OFF control, reverse current blocking, and rapid device turnoff to protect bus integrity. The controller also supports soft-start functionality to reduce bus transients. It is housed in an 8-pin SOIC package, designed for surface mounting.

This ORing controller is particularly suited for applications such as N+1 power supplies, server blades, and telecom systems where robust and uninterrupted power delivery is critical.
