TPS2149IDGN Description

Short technical summary and product information.

The Texas Instruments TPS2149IDGN is a versatile power management IC designed for USB bus-powered hub applications. It integrates two 5V high-side MOSFET power switches and a 3.3V low-dropout (LDO) voltage regulator into a single 8-pin HVSSOP package.

 

This device provides a complete power management solution, featuring independent thermal and short-circuit protection for both the LDO and each switch. It includes an overcurrent indicator and a transient filter, operating within a 2.9V to 5.5V range. The switches are rated for 200mA with a typical Rds On of 340mΩ, and feature active-low enable inputs compatible with CMOS and TTL logic.

 

With its compact size and integrated functionality, the TPS2149IDGN is ideal for space-constrained designs. It simplifies power management in USB hubs, keyboards, monitors, and other bus-powered devices, contributing to efficient power distribution and system protection.
