Found 1 results for TPS259814ARPWR datasheet pin description pinout R-PW package 14 pin.

I found critical mismatches: this part is officially a 10-pin TI RPW/VQFN-HR eFuse, but the current symbol/footprint exposes 14 terminals/pads, the package property is set to TO, and all pin types are still Unspecified. Full review is in the TPS259814ARPWR Part Review project file.

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, 3v3, gnd_1 gnd_2 etc NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

Grouped the valid TPS259814ARPWR datasheet pins 1–10 by function and updated their Pin Type, Section, Pin Group, Pin Description, and Pin Orientation. I intentionally did not group the extra duplicate terminals EN/UVLO_2, ~FLT_2, DVDT_2, and ITIMER_2 because they are pins 11–14, which do not exist on the official 10-pin RPW package and should be removed or fixed separately.

Footprint review

The layout currently contains pads matching the 14 schematic terminals: pins/pads for EN/UVLO_1, ~EN~/OVLO, PG, ~FLT_1, IN, OUT, DVDT_1, GND, ILM, ITIMER_1, plus duplicated EN/UVLO_2, ~FLT_2, DVDT_2, and ITIMER_2.

The footprint asset name is TPS259474LRPWR.kicad_mod, which appears to be for a different MPN family and should be treated as suspicious unless intentionally shared and verified against the TI RPW0010A package drawing.

Mismatches / issues flagged

Pin count mismatch — critical
- Project has 14 terminals/pads.
- Official TI information for TPS259814ARPWR indicates 10 pins in RPW/VQFN-HR.
- Extra project pins: 11 EN/UVLO_2, 12 ~FLT_2, 13 DVDT_2, 14 ITIMER_2.
Package mismatch — critical
- Project property Package or Case Code is TO, which does not match official RPW / VQFN-HR 10-pin package.
Footprint asset mismatch — critical
- Current footprint asset is named TPS259474LRPWR.kicad_mod, not TPS259814ARPWR.
- The current layout exposes 14 pads, inconsistent with the official 10-pin RPW package.
Pin naming mismatch — moderate
- Pin 2 is shown as ~EN~/OVLO; expected datasheet naming is EN/OVLO or equivalent active-low enable/OVLO notation.
- Pin 4 ~FLT_1 should map to FLT / active-low fault output. The suffix _1 suggests duplicated imported pins.
- Pins 7 and 10 have _1 suffixes, again suggesting duplicate import artifacts.
Missing pin metadata — moderate
- All 14 terminals currently have Pin Type: Unspecified.
- Pin descriptions, sections, pin groups, and orientations are not populated.
Description typo — low
- Project description says 6-m eFuse; this should likely be 6-mΩ eFuse.

Recommended fixes

Replace or correct the symbol to exactly 10 terminals for TPS259814ARPWR RPW package.
Remove or flag the extra pins 11–14 after confirmation.
Replace/verify the footprint against TI RPW0010A / 10-pin VQFN-HR mechanical drawing.
Update Package or Case Code from TO to RPW0010A or VQFN-HR-10 (RPW).
Update pin types and descriptions per the expected pinout table above.
Consider updating Designator Prefix from IC to U, unless your library convention intentionally uses IC.
Correct the description to include 6-mΩ.

Description

Electronic Fuse Regulator High-Side 10A 10-VQFN-HR (2x2)

The TPS25981xx 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 and excessive inrush current. Output slew rate and inrush current can be adjusted using a single external capacitor. Loads are protected from input overvoltage conditions by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current (during startup) or breaking the circuit (during steady-state). The overcurrent protection threshold as well as the transient overcurrent blanking timer are useradjustable. The current limit control pin also functions as an analog load current monitor. The devices are available in a 2-mm × 2-mm, 10- pin HotRod™ QFN package for improved thermal performance and reduced system footprint. The devices are characterized for operation over a junction temperature range of –40°C to +125°C.

• Wide operating input voltage range: 2.7 V to 16 V – 20-V absolute maximum • Integrated FET with low on-resistance: RON = 6 mΩ (typ.) • Fast overvoltage protection – Adjustable overvoltage lockout (OVLO) with 1.2-μs (typ.) response time • Overcurrent protection with load current monitor output (ILM) – Circuit-breaker response – Adjustable threshold (ILIM) 1.5 A – 11 A • ±10% accuracy for ILIM > 5 A – Adjustable transient blanking timer (ITIMER) to allow peak currents up to 2 × ILIM – Output load current monitor accuracy: ±10% (IOUT ≥ 3 A) • Fast-trip response for short-circuit protection – 640-ns (typ.) response time – Adjustable (2 × ILIM) and fixed thresholds • Active high enable input with adjustable undervoltage lockout threshold (UVLO) • Active low enable input with adjustable undervoltage lockout threshold (OVLO) • Adjustable output slew rate control (dVdt) • Option to drive external FET for reverse current blocking in disabled/OFF state • Overtemperature protection • Quick Output Discharge • Digital outputs – Power Good (PG) and fault indication (FLT) • UL 2367 recognition (pending) • IEC 62368 CB certification (pending) • Small footprint: QFN 2-mm × 2-mm, 0.45-mm pitch
