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