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 | GATE | output | Connects to the gate of the external N-channel high-side MOSFET; sources approximately 15 µA when enabled and the charge pump generates 9 V-12 V gate-to-source drive. |+| 2 | DGND | power_in | Digital ground for the controller. |+| 3 | TIMER | output | Capacitor from TIMER to ground sets the circuit-breaker deglitch time; the latch trips at about 0.5 V, and a minimum 50 pF is strongly recommended in high-power or high-temperature applications to prevent false triggering. |+| 4 | VREG | output | Output of the internal low-dropout regulator, less than 5.5 V, for the device; a 0.1 µF ceramic capacitor to ground is recommended for noise rejection. |+| 5 | VSENSE | input | Power-good sense input; PWRGD is pulled low when VSENSE falls below approximately 1.23 V (20 µs deglitch). |+| 6 | AGND | power_in | Analog ground; connect to DGND as close as possible. |+| 7 | ISENSE | input | Current-sense input connected to the MOSFET drain; an overcurrent is assumed when ISENSE is pulled below ISET, and VI(ISENSE) must never exceed VI(IN). |+| 8 | IN | power_in | Input voltage supply (3 V to 13 V) that powers the device and the external MOSFET; the device supports 3 V, 5 V, or 12 V operation and remains disabled until IN is established. |+| 9 | AGND | power_in | Analog ground; connect to DGND as close as possible. |+| 10 | ISET | input | Sets the circuit-breaker threshold through an external resistor to IN, with a 50 µA internal current source; VI(ISET) must never exceed VI(IN). |+| 11 | FAULT | output | Open-drain overcurrent fault output that is pulled low and latches off the device when TIMER reaches 0.5 V. |+| 12 | PWRGD | output | Open-drain power-good output, asserted low when VSENSE is below the approximately 1.23 V reference; it is pulled up to its pullup rail while the device is disabled. |+| 13 | ENABLE | input | Active-high enable on the TPS2331 (active-low on the TPS2330); holding it in the disable state for more than 50 µs discharges the gate and the output bulk capacitance. |+| 14 | DISCH | output | Connects to the source of the external N-channel MOSFET to discharge the load when the MOSFET is disabled, and serves as the reference for internal gate-voltage clamp circuitry. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-14 |+| Category | Power Management (PMIC) |+| Pins | 14 |++## CAD (KiCad official)++- Symbol: `TPS2331IDR`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)+- 3D model files: `tps2331idr-etched.step` / `tps2331idr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2331idr.step` / `tps2331idr.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/lit/ds/symlink/tps2331.pdf) (29 pp, sha256 `d6a67c69fef8f4da`, retrieved 2026-10-07, tier: manufacturer)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
