3 Description
The TPS25924x 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 TPS25924x
output and the gate driven by BFET to prevent
current flow from load to source (see Figure 43).

DESCRIPTION
O
Connect this pin to the gate of a blocking NFET. See the Feature Description
section. This pin can be left floating if it is not used
O
Tie a capacitor from this pin to GND to control the ramp rate of OUT at device
turnon
This is a dual function control pin. When used as an ENABLE pin and pulled
down, it shuts off the internal pass MOSFET and pulls BFET to GND. When
I
pulled high, it enables the device and BFET.
As an UVLO pin, it can be used to program different UVLO trip point via
external resistor divider
