TPS2592AADRCT (TEXAS INSTRUMENTS)

The TPS2592AADRCT is a 12V eFuse with over voltage protection and blocking FET control. It uses few external components and provides multiple protection modes. It is a robust defense against overloads, shorts circuits, voltage surges, excessive inrush current and reverse current. Current limit level can be set with a single external resistor. Over voltage events are limited by internal clamping circuits to a safe fixed maximum, with no external components required. Applications with particular voltage ramp requirements can set dV/dT with a single capacitor to ensure proper output ramp rates. Many systems, such as SSDs, must not allow holdup capacitance energy to dump back through the FET body diode onto a drooping or shorted input bus. The BFET pin is for such systems. An external NFET can be connected "back to back (B2B)" with the TPS2592Ax output and the gate driven by BFET to prevent current flow from load to source.
