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 | DRISR | output | Synchronous rectification MOSFET drive output. Drives the gate of the internal SR MOSFET; drive output voltage typ. ≥3.7V at VCC=5V. |+| 2 | VDET | bidirectional | Synchronous rectification sense input and dynamic function output; connects to internal MOSFET DRAIN through a resistor. Senses drain-source voltage for SR turn-on/off decisions and provides periodic pulse for output voltage detect. |+| 3 | AREF | input | Programs a voltage reference via a resistor from AREF to GND to enable the synchronous rectification MOSFET drive signal. Sets the reference current I_AREF. |+| 4 | VCC | power_in | Power supply pin, connected with the system output. Operating range 3.3-5.5V; absolute max 7.5V. Startup voltage typ. 3.1V, UVLO typ. 2.8V. |+| 5 | DRAIN | passive | Drain pin of the internal N-Channel MOSFET. The drain voltage signal can be obtained from this pin. Rated 50V, 20A continuous / 80A pulsed. |+| 6 | GND | power_in | Source pin of the internal MOSFET, connected to Ground. Pins 6, 7, 8 are tied together and carry secondary current to the exposed DRAIN pad. |+| 7 | GND | power_in | Source pin of the internal MOSFET, connected to Ground. Pins 6, 7, 8 are tied together and carry secondary current to the exposed DRAIN pad. |+| 8 | GND | power_in | Source pin of the internal MOSFET, connected to Ground. Pins 6, 7, 8 are tied together and carry secondary current to the exposed DRAIN pad. |+| EP | DRAIN | passive | Exposed pad - drain of the internal MOSFET. Secondary current should flow from GND (pins 6,7,8) to this DRAIN pad. Must be soldered to a PCB copper pour for thermal and electrical connection. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SO-8-EP |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `APR34309CAMPTR-G1MPTR-G1`++## CAD (KiCad official)++- Symbol: `APR34309CAMPTR-G1`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8-EP (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/apr34309camptr-g1-datasheet.pdf) (11 pp, sha256 `9458611cf2a2321d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
