Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | REF | input | Reference input. High-impedance sense input compared internally against the on-chip 2.495 V bandgap; when the divider voltage at REF reaches Vref the device begins conducting cathode-to-anode. Reference input current is typically 2 uA (max 4 uA). |+| 2 | ANODE | power_in | Common anode. Normally connected to ground (or the low side of the divider network) and forms the return path for the cathode shunt current. |+| 3 | CATHODE | power_in | Shunt current/voltage input. Sinks current from the supply through an external series/pull-up resistor to regulate Vka; continuous cathode current range is 1 mA to 100 mA (absolute max -100 to +150 mA), Vka up to 36 V (abs max 37 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TL432AIM3/TR`+- `TL432AIM3AIMK/TR`+- `TL432AIM3AIM5/TR`++## CAD (KiCad official)++- Symbol: `TL432AIM3`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/tl432aim3-datasheet.pdf) (26 pp, sha256 `cc40a4a8815eed85`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
