The TPS2491DGSR with Hot Swap Voltage Controllers Retry Pos Hi-Voltage Pwr-Limiting manufactured by Texas Instruments is a Hybrid integrated circuit (HIC) designed to offer a hot swap protection. It is a power limiting device is used in high-power supplies with the intention of protecting equipment, power systems, and components from damage due to short-circuit overloads of a single load or several connected loads. This Hybrid chip features high-current, high-voltage operation in a small package size. It is a dual channel device that offers integrated fault signal retry, hysteresis protection, and adjustable current limiting, allowing it to meet a variety of hot-swap applications. The chip also provides over-current, over-voltage, and under-voltage protection. It is available in a PowerSO-10 package.
