The TPS2490DGSG4, manufactured by Texas Instruments, is a Hot Swap Controller designed to enable safe insertion and removal of circuit boards in live systems. It is particularly effective in managing inrush current to prevent disturbances on the power supply that can lead to drops in voltage affecting other system components. With its advanced features including programmable current limit, under-voltage lockout, and power good reporting, it is an essential component in server farms, telecommunications equipment, and network switches where maintenance and upgrade need to be performed without disrupting operation. The TPS2490DGSG4 can control voltages up to 80V, making it versatile for a broad range of applications. Integrated features such as overcurrent and overtemperature protection enhance the safety and reliability of the systems in which it is used. Its package, the TSSOP (Thin Shrink Small Outline Package), is designed for compact PCB layouts. The TPS2490DGSG4's blend of power management and protection features make it a critical component for high-availability systems.
