12V eFuse with Integrated Blocking FET Driver - TPS2592AA

TPS2592AA (ACTIVE)

12V eFuse with Integrated Blocking FET Driver

Description

The TPS2592xx family of eFuses is a highly integrated circuit protection and power management solution in a tiny package. The devices use few external components and provide multiple protection modes. They are 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 and current limit set has a typical accuracy of ±15%. Over voltage events are limited by internal clamping circuits to a safe fixed maximum, with no external components required. TPS2592Ax devices provide over voltage protection (OVP) for 12V systems and TPS2592Bx devices for 5V systems. In cases with particular voltage ramp requirements, a dV/dT pin is provided that can be programmed 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 TPS2592 output and the gate driven by BFET to prevent current flow from load to source.
