TPS2393APW

The Texas Instruments TPS2393APW is an active hot swap controller housed in a 14-TSSOP package. It is engineered for applications requiring robust power management in -48V distributed power systems, central office switching, and wireless base stations.

This device offers a wide input supply range from -20V to -80V, with a transient rating up to -100V. Key electrical features include adjustable OVLO, adjustable soft start, fault output, overcurrent protection, overvoltage protection, a power good signal, short circuit protection, and adjustable UVLO. The overcurrent response is characterized by current limiting, and the fault response includes auto-retry functionality.

With a typical quiescent current of 1.05 mA, the TPS2393APW is suitable for power-sensitive designs. The controller supports programmable features such as current limit, fault timeout, OVP, slew rate, and UVLO, allowing for customization to specific application needs. The surface mountable 14-TSSOP package (0.173", 4.40mm width) facilitates integration into compact designs.

Designed for reliability, it includes insertion and removal detection delay, an extended debounce delay, and an output fault timer to prevent nuisance trips. The open-drain power good (PG) and fault (FAULT) outputs provide essential status monitoring capabilities.
