CC6920BSO-20A from Cross chip, 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 IP+ passive Current sampled positive terminal. One of the two tied primary-conductor input pads (pins 1-2). Input current flows in from IP+ (pins 1,2) to IP- (pins 3,4). Rated 40 A continuous / 100 A peak (3 s); primary conductor resistance ~0.9 mΩ.
2 IP+ passive Current sampled positive terminal (paralleled with pin 1). Second pad of the isolated primary current input.
3 IP- passive Current sampled negative terminal. One of the two tied primary-conductor return pads (pins 3-4). 3500 VRMS isolation between primary (IP+/IP-) and secondary (signal) sides.
4 IP- passive Current sampled negative terminal (paralleled with pin 3). Second pad of the isolated primary current return.
5 GND power_in Signal ground for the secondary (Hall sensor and output amplifier) side. Reference for VCC, VOUT and VZCR.
6 VZCR output Zero-current reference signal output, nominally VCC/2 (≈1.65 V at VCC=3.3 V). Can be used as a mid-supply reference for downstream amplifiers or ADCs. Source current ≤400 µA, sink current ≤3000 µA.
7 OUT output Analog voltage output proportional to sensed primary current: VOUT = VCC/2 + 0.066 × IP(A) for the -20A variant (66 mV/A). Linear output range 0.2-4.8 V at VCC=3.3 V; drives up to 6 mA source / 30 mA sink into ≥1.5 kΩ load.
8 VCC power_in Secondary-side power supply, 3.0-3.6 V (3.3 V nominal). Typical supply current 20 mA (25 mA max) with OUT unloaded. Absolute maximum 7 V. Bypass with 0.1 µF to GND close to the pin.

CAD (KiCad official)

  • Symbol: CC6920BSO-20A
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cc6920bso-20a-etched.step / cc6920bso-20a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cc6920bso-20a.step / cc6920bso-20a.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
cc6920bso-20a.step 122 KB You want the bare part, or you mark your own boards.
cc6920bso-20a-etched.step 3.0 MB You want the part with CC6920BSO-20A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 704 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Cross chip datasheet (23 pp, sha256 bf0f27c31807521e, 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).
