Hot Swap Controllers

TPS2393DBT Description

The TPS2393DBT is a hot swap controller designed for managing the insertion and removal of circuit boards in live systems, ensuring reliable operation and protection against transient voltages and currents. Manufactured by Texas Instruments, this device is housed in a 44-pin TSSOP package, making it suitable for surface mount applications. Despite its obsolete status, the TPS2393DBT remains a robust solution for systems requiring high reliability and protection.

Key technical specifications include a supply current of 1.05 mA, which ensures minimal power consumption during operation. The device is designed without internal switches, allowing for greater flexibility in system design. It features programmable current limit, fault timeout, overvoltage protection (OVP), slew rate, and undervoltage lockout (UVLO), providing extensive control over the hot swap process. The TPS2393DBT also supports an auto retry feature, enhancing its robustness in handling transient faults.
