TPS2490DGSG4 Description

Short technical summary and product information.

The TPS2490DGSG4 from Texas Instruments is a hot swap controller designed for robust power system management. It supports a wide operating voltage range from 9V to 80V, making it suitable for various industrial and high-voltage applications.

 

Key features include adjustable current limiting, adjustable soft start, and a latched fault response, providing comprehensive protection against overcurrent and short-circuit conditions. The device also offers an adjustable UVLO (undervoltage lockout) and a power good signal for downstream coordination.

 

This controller is housed in a compact 10-VSSOP package, suitable for surface mount applications. Its design facilitates the use of low R DS(on) external N-channel MOSFETs, optimizing power efficiency. The programmable fault timer helps protect the external MOSFET and prevent nuisance shutdowns.

 

With a typical quiescent current of 0.45 mA, the TPS2490DGSG4 is designed for power-sensitive applications. Its general-purpose nature and protective features make it a versatile component for ensuring system reliability during power transitions.
