I've created a plan and started work on it.

Plan

#Goal

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.

#Implementation plan

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:
1. Input capacitors for power supply bypassing.
2. Output capacitors for load stability and filtering.
3. 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.

#Success criteria

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.

Description

IC SURGE STOPPER 2.7V~23V VQFN-10-HR(2x2)

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. • Wide operating input voltage range: 2.7V to 23V – 28V absolute maximum – Withstands negative voltages up to –15V • Integrated back-to-back FETs with low onresistance: RON = 28.3mΩ (typical) • Ideal diode operation with true reverse-current blocking • Fast overvoltage protection – Overvoltage clamp (OVC) with pin-selectable threshold (3.8V, 5.7V, 13.8V) and 5μs (typical) response time OR – Adjustable overvoltage lockout (OVLO) with 1.2μs (typical) response time • Overcurrent protection with load current monitor output (ILM) – Active current limit OR circuit-breaker options – Adjustable threshold (ILIM) 0.5A to 6A • ±10% accuracy for ILIM > 1A – Adjustable transient blanking timer (ITIMER) to allow peak currents up to 2 × ILIM – Output load current monitor accuracy: ±6% (IOUT ≥ 1A) • Fast-trip response for short-circuit protection – 500ns (typical) response time – Adjustable (2 × ILIM) and fixed thresholds • Active high enable input with adjustable undervoltage lockout threshold (UVLO) • Adjustable output slew rate control (dVdt) • Overtemperature protection • Digital outputs – Priority power MUX control (AUXOFF) and fault indication (FLT) or – Power Good indication (PG) with adjustable threshold (PGTH) • UL 2367 recognition – File No. E339631 – RILM ≥ 750Ω • IEC 62368-1 CB certified • Small footprint: QFN 2mm × 2mm, 0.45mm pitch
