3 Description
The TPS2592Ax 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. 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 (see Figure 40).
