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 | ADR2 | input | SMBus address line 2 is a three-state strap that must be connected to GND, VDD, or left floating. |+| 2 | ADR1 | input | SMBus address line 1 is a three-state strap that must be connected to GND, VDD, or left floating. |+| 3 | ADR0 | input | SMBus address line 0 is a three-state strap that must be connected to GND, VDD, or left floating. |+| 4 | VDD | power_out | Internally sub-regulated 4.5V bias supply output that requires a 1 µF capacitor to ground for bypassing. |+| 5 | CL | input | Current limit range select: connecting to GND sets the over-current threshold to 25 mV, and connecting to VDD sets it to 46 mV. |+| 6 | CB | input | Circuit breaker range select: connecting to GND sets the trip point to 1.8 times the over-current threshold, and connecting to VDD sets it to 3.6 times. |+| 7 | FB | input | Power Good feedback input, where an external OUT resistor divider sets the PGD switching point at a 1.167 V threshold with an internal 24 µA hysteresis current source. |+| 8 | RETRY | input | Fault retry select: grounding this pin gives continual retries during a fault, while connecting it to VDD latches the device off during a fault. |+| 9 | TIMER | passive | Timing capacitor connection that sets the insertion time delay, fault timeout period and restart timing. |+| 10 | PWR | input | Power limit set: an external resistor here, together with the current sense resistor RS, sets the maximum power dissipation allowed in the external series pass MOSFET. |+| 11 | PGD | output | Open-drain Power Good output that is high when FB is above 1.167 V and the input supply is within its under-voltage and over-voltage thresholds, and that must be pulled up through an external resistor. |+| 12 | OUT | passive | Output feedback connected to the output rail (external MOSFET source), used to determine MOSFET VDS for power limiting and to monitor output voltage; the Out to GND rating is -1 to 20V. |+| 13 | GATE | output | Gate drive output connected to the external MOSFET gate, with the gate voltage limited by an internal 18.8 V zener clamp. |+| 14 | SENSE | input | Current sense input, where the voltage across the current sense resistor RS is measured from VIN to this pin. |+| 15 | VIN | power_in | Positive supply input with an operating range of 2.9 V to 17 V, which should have a small ceramic bypass capacitor placed close to the pin. |+| 16 | UVLO/EN | input | Under-voltage lockout and enable input, where an external divider sets the turn-on threshold, the enable threshold is 1.16 V, and an internal 23 µA hysteresis current source is provided; it can also be used for remote shutdown. |+| 17 | OVLO | input | Over-voltage lockout input, where an external divider sets the turn-off threshold, the disable threshold is 1.16 V, and an internal 23 µA hysteresis current source is provided. |+| 18 | GND | power_in | Circuit ground. |+| 19 | SDA | bidirectional | SMBus data pin. |+| 20 | SCL | input | SMBus clock pin. |+| 21 | SMBA | output | SMBus alert line, active low. |+| 22 | VREF | power_out | Internally generated precision 2.73V reference used for analog-to-digital conversion, which requires a 1 µF capacitor to ground for bypassing. |+| 23 | DIODE | passive | External diode connection for a diode-configured NPN transistor used for temperature monitoring. |+| 24 | VAUX | input | Auxiliary voltage input for telemetry from an external source, with a full-scale input of 1.16 V. |+| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WQFN-24(4x5) |+| Category | Circuit Protection |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `LM25066IPSQX`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x5mm_P0.5mm_EP2.65x3.65mm`+- 3D model: WQFN-24(4x5) (KiCad packages3D, STEP)+- 3D model files: `lm25066ipsqx-etched.step` / `lm25066ipsqx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm25066ipsqx.step` / `lm25066ipsqx.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/lm25066i) (59 pp, sha256 `af8bdb207ef7d7d6`, retrieved 2026-10-08, tier: lcsc)+- **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.
