Part Information Review and Update
Thought for 1 min 55 sec
I reviewed the current part project for TPS2117DRLR.
- The Datasheet URL is already present and populated, so no web search/update was needed.
- I used the datasheet as the source of truth and checked that the project pin count matches the datasheet pin count exactly, which is the correct review method for part projects
Table
| Area | Status | Notes |
|---|---|---|
| MPN | OK | TPS2117DRLR matches datasheet |
| Manufacturer | OK | Texas Instruments |
| Datasheet URL | OK | Present and points to TI datasheet |
| Pin count | OK | 8 pins in project, 8 pins in datasheet |
| Pin names | OK | Terminal names match datasheet pin names/function split |
| Footprint pad count | OK | Footprint has 8 pads, matching DRL package |
| Package metadata | Mismatch | Project says SOT; datasheet is more specific: DRL, 8-pin SOT-5X3 |
| Part type | Mismatch | Project says Electromechanical Components; datasheet indicates a power mux / power switch IC |
| Designator prefix | Likely mismatch | Project says IC; typical IC prefix should be U |
| Pin types | Mismatch | All pins are Unspecified; datasheet supports proper typing |
| Pin descriptions | Missing | No pin descriptions set on any terminal |
Table

| Switchover modes | Priority, Manual, Diode |
| Switchover behavior | Break-before-make |
| Switchover time | 12 us typ @ 1.8 V, 15 us @ 3.3 V, 16 us @ 5 V |
| Temperature range | -40 C to 105 C ambient |
| Package | DRL / 8-pin SOT-5X3 |
| Pitch | 0.5 mm |
| Exposed pad | No |
Table
| Datasheet pin | Project terminal | Status | Suggested pin type | Suggested short description |
|---|---|---|---|---|
| 1 GND | GND | OK | Ground | Device ground |
| 2 VOUT | VOUT_1 | OK | Power Out | Output power |
| 3 VIN1 | VIN1 | OK | Power In | Channel 1 input |
| 4 PR1 | PR1 | OK | Input | Priority select input |
| 5 MODE | MODE | OK | Input | Mode select input |
| 6 VIN2 | VIN2 | OK | Power In | Channel 2 input |
| 7 VOUT | VOUT_2 | OK | Power Out | Output power |
| 8 ST | ST | OK | Output | Open-drain status |
Table
| Check | Result |
|---|---|
| Package lead count | Matches: 8 leads in datasheet, 8 pads in footprint |
| Exposed pad presence | Matches: none in datasheet, none apparent in footprint |
| Symbol terminal set | Matches all 8 datasheet pins |
| Symbol metadata quality | Needs improvement |
| Footprint metadata specificity | Needs improvement |
- Part Type is incorrect
- Current:
Electromechanical Components - Should be something like:
Power Multiplexer,Power Switch IC, or similar IC category
- Current:
- Package or Case Code is too vague
- Current:
SOT - Better:
DRL,8-pin SOT-5X3, orDRL0008A
- Current:
- Designator Prefix is nonstandard
- Current:
IC - Better:
U
- Current:
- All pin types are unset
- Every terminal is currently
Unspecified
- Every terminal is currently
- All pin descriptions are missing
- The datasheet provides enough information to populate concise descriptions
- Project description could be cleaner
- Current description is usable, but a crisper library-style description would be better, per the recommended part-project sync workflow
Table
| Property | Recommended value |
|---|---|
| Manufacturer Part Number | TPS2117DRLR |
| Manufacturer Name | Texas Instruments |
| Part Type | Power Multiplexer |
| Package or Case Code | DRL or 8-pin SOT-5X3 |
| Designator Prefix | U |
| Datasheet URL | Keep current TI URL |
| Operating Voltage | 5.5 |
| Max Current | 4 |
| Operating Temperature | -40°C to +105°C |
The pinout and footprint pad count look correct, so there are no obvious symbol-to-datasheet or pad-count-to-package mismatches. The main problems are metadata quality and missing terminal properties:
- wrong part category
- vague package code
- nonstandard designator prefix
- missing pin types
- missing pin descriptions
If you want, I can next fix the project properties and populate all 8 terminal pin types/descriptions.
Fix metadata and pins
Use U prefix
Check footprint details
