Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | power_in | Power input connecting to the drain of the internal FET; operating range 4.5 V to 60 V. |+| 2 | IN | power_in | Power input connecting to the drain of the internal FET; operating range 4.5 V to 60 V. |+| 3 | B_GATE | output | Blocking FET gate driver output that connects to the gate of the external NFET, or is left floating if no external FET is used. |+| 4 | DRV | output | Blocking FET fast pulldown switch drive that connects to the gate of the external pulldown switch, or is left floating if the external N-FET is not used. |+| 5 | IN_SYS | power_in | Power input and supply voltage of the device, connected to the source of the external blocking FET or shorted to IN if no blocking FET is used. |+| 6 | UVLO | input | Input for setting the programmable undervoltage lockout threshold, with an undervoltage event turning off the internal FET and asserting FLT; connect to GND to select the internal default threshold. |+| 7 | OVP | input | Input for setting the programmable overvoltage protection threshold, with an overvoltage event turning off the internal FET and asserting FLT; connect to GND to select the internal default threshold. |+| 8 | GND | power_in | Connect to system ground. |+| 9 | dVdT | bidirectional | A capacitor from this pin to GND sets the output voltage slew rate. |+| 10 | ILIM | bidirectional | A resistor from this pin to GND sets the overload and short-circuit current limit (recommended 3 to 30 kOhm). |+| 11 | MODE | input | Mode selection pin for overload fault response: open latches off, shorted to GND selects auto-retry. |+| 12 | SHDN | input | Shutdown pin; pulling it low puts the device in low power shutdown, and cycling it resets a latched-off fault. |+| 13 | IMON | output | Analog current monitor output sourcing a scaled-down ratio of the internal FET current (27.9 uA/A typical), converted to voltage by a resistor to GND; leave floating if unused. |+| 14 | FLT | output | Open-drain fault event indicator; leave floating or connect to GND if unused. |+| 15 | PGTH | input | PGOOD comparator input. |+| 16 | PGOOD | output | Active-high power-good output that goes high when PGTH crosses the V(PGTHR) threshold and the internal FET is enhanced; connect to GND or leave floating if unused. |+| 17 | OUT | power_out | Power output of the device. |+| 18 | OUT | power_out | Power output of the device. |+| 19 | N.C | unconnected | No connect. |+| 20 | N.C | unconnected | No connect. |+| 21 | N.C | unconnected | No connect. |+| 22 | N.C | unconnected | No connect. |+| 23 | N.C | unconnected | No connect. |+| 24 | N.C | unconnected | No connect. |+| 25 | PowerPAD | power_in | Connect the PowerPAD to the GND plane for heat sinking; do not use it as the only electrical connection to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-24(4x4) |+| Category | Circuit Protection |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `TPS26631RGER`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.6x2.6mm`+- 3D model: VQFN-24(4x4) (KiCad packages3D, STEP)+- 3D model files: `tps26631rger-etched.step` / `tps26631rger-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps26631rger.step` / `tps26631rger.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps2663) (60 pp, sha256 `63ce6e9453e4499b`, retrieved 2026-10-06, tier: lcsc)+- **Datasheet language:** Chinese.
