The Texas Instruments TPS2399DGK is an active hot swap controller IC designed for applications requiring robust power protection. It supports a wide input supply range from -36 V to -80 V, with a transient rating up to -100 V, making it suitable for -48V distributed power systems and redundant negative voltage supplies.
Key features include adjustable current limit, adjustable soft start, fault output, overcurrent protection, a power good signal, and short circuit protection. The device also incorporates an adjustable UVLO (undervoltage lockout) and an auto-retry fault response mechanism. Programmable features extend to current slew rate and a fault timer to prevent nuisance trips.
This hot swap controller is housed in an 8-pin VSSOP package, suitable for surface mounting. Its design optimizes for improved transient response and provides an open-drain power good output. The typical quiescent current is 0.7 mA, with a maximum of 1 mA.
The TPS2399DGK is ideal for engineers designing systems that require controlled power-up and protection against voltage transients and overcurrent conditions in negative voltage rail applications.
