The TPS249x are easy-to-use, positive high voltage, 10-pin Hot Swap Power Manager devices that safely drive an external N-channel MOSFET switch. The power limit and current limit (both are adjustable and independent of each other) ensure that the external MOSFET operates inside a selected safe operating area (SOA) under the harshest operating conditions. Applications include inrush current limiting, electronic circuit breaker protection, controlled load turn-on, interfacing to down-stream DC-to-DC converters, and power feed protection. These devices are available in a small, space-saving 10-pin VSSOP package and significantly reduce the number of external devices, saving precious board space. The TPS249x is supported by application notes, an evaluation module, and a design tool.
