3 Description
The TPS25923x 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
TPS25923x 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. Leave this pin 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
