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 | VCC | power_in | Low-side and logic supply voltage. Recommended operating range 10V to 20V (absolute max 25V). Provides the internal logic bias and low-side gate drive rail. |+| 2 | HIN | input | Logic input for the high-side driver channel. Compatible with 3.3V/5V/15V logic (VIH >= 2.4V, VIL <= 0.6V). Referenced to COM. |+| 3 | LIN | input | Logic input for the low-side driver channel. Compatible with 3.3V/5V/15V logic (VIH >= 2.4V, VIL <= 0.6V). Referenced to COM. |+| 4 | COM | power_in | Logic ground and low-side driver return. Common reference for VCC, HIN, LIN, and the LO output. |+| 5 | LO | output | Low-side gate driver output. Drives the gate of the low-side N-channel MOSFET/IGBT; swings between COM and VCC. Typical peak sink/source ~800mA/1.2A. |+| 6 | VS | power_in | High-side driver floating return (source of the high-side MOSFET / emitter of the IGBT). Offset voltage range -5V to 600V; allowable dVs/dt = 50 V/ns. |+| 7 | HO | output | High-side floating gate driver output. Drives the high-side N-channel MOSFET/IGBT gate; swings between VS and VB. |+| 8 | VB | power_in | High-side floating supply (bootstrap). Recommended VB = VS + 10V to VS + 20V (absolute max 625V referenced to COM). Typically supplied via a bootstrap diode and capacitor from VCC. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LINKOSEMI |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LKS523`++## CAD (KiCad official)++- Symbol: `LKS523`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LINKOSEMI datasheet](docs/lks523-datasheet.pdf) (12 pp, sha256 `25023009ae00348c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
