Application Schematic
3 Description
The TPS25925x/6x 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. 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. TPS25926x
devices provide over voltage protection (OVP) for 12-
V systems and TPS25925x devices for 5-V 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.

DESCRIPTION
Connect a capacitor from this pin to GND to control the ramp rate of OUT
voltage 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. When pulled high, it enables the
device
As an UVLO pin, it can be used to program different UVLO trip point via
external resistor divider
