Description

The TPS2306 Hot Swap Power Manager (HSPM) IC provides hot-swap control, fault handling and power supply sequencing of two positive voltage supplies. The TPS2306 operates over a wide supply range allowing single part inventory for a variety of output voltages.

During the transient period of a live insertion or hot-swap event, the TPS2306 actively limits the inrush current to the plug-in module. An on-chip linear current amplifier (LCA) provides closed-loop control of the current sourced to the load circuitry on the module. Subsequently, during normal steady-state loading conditions and in conjunction with an internal high-voltage charge pump, the LCA provides direct gate drive to fully enhance the external NMOS pass devices.
