LKS523

LINKOSEMI · Isolators - Gate Drivers · SOP-8

LKS523 from LINKOSEMI, in a SOP-8. 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: LINKOSEMI datasheet (12 pp, sha256 25023009ae00348c, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
