Develop a complete editable schematic for the TPS259474LRPWR eFuse by integrating the eFuse with all necessary supporting circuitry including resistors, capacitors, and other required components that meet the device's electrical requirements. This schematic should be ready for schematic review and subsequent PCB-layout integration.
Create a new editable design project for the complete schematic since the current TPS259474LRPWR part project is read-only.
Add the TPS259474LRPWR eFuse to the new project from the Flux library.
Research and identify all necessary supporting components for the TPS259474LRPWR based on its datasheet recommendations, which may include:
Input capacitors for power supply bypassing.
Output capacitors for load stability and filtering.
Resistors, such as pull-up or current-sense resistors, if required by the device configuration.
Place the identified supporting components (generic resistors and capacitors from the Flux library or specific approved parts as needed).
Wire and connect the components to the TPS259474LRPWR following the recommended reference design and datasheet guidelines (ensuring proper orientation and connection for power management and fault handling).
Validate the schematic connections and component values to ensure proper functionality and compliance with the eFuse requirements.
Update the project description and properties to reflect the design intent and readiness for PCB layout.
The new editable project includes the TPS259474LRPWR eFuse and all required supporting components.
The schematic connections follow the TPS259474LRPWR datasheet recommendations and ensure all necessary elements (resistors, capacitors, etc.) are correctly incorporated.
The design is fully reviewable and ready to advance into PCB layout phase.

The TPS25947xx family of eFuses is a highly
integrated circuit protection and power management
solution in a small package. The devices provide
multiple protection modes using very few external
components and are a robust defense against
overloads, short-circuits, voltage surges, reverse
polarity and excessive inrush current. With integrated
back-to-back FETs, reverse current flow from output
to input is blocked at all times, making the devices an
excellent choice for power MUX/ORing applications
as well as systems which need load side energy
hold up storage in case input power supply fails. The
devices use linear ORing based scheme to establish
an almost zero DC reverse current and emulate ideal
diode behavior with minimum forward voltage drop
and power dissipation.
Output slew rate and inrush current can be adjusted
using an external capacitor. Loads are protected
from input overvoltage conditions either by clamping
the output to a safe fixed maximum voltage (pin
selectable), or by cutting off the output if input
exceeds an adjustable overvoltage threshold. The
devices respond to output overload by actively limiting
the current or breaking the circuit. The output current
limit threshold as well as the transient overcurrent
blanking timer are user adjustable. The current limit
control pin also functions as an analog load current
monitor.
The devices are available in a 2mm × 2mm, 10-
pin HotRod™ QFN package for improved thermal
performance and reduced system footprint.
The devices are characterized for operation over a
junction temperature range from –40°C to +125°C.
