HY2212-BB3A

HYCON Tech · Battery Management · SOT-23-6

HY2212-BB3A from HYCON Tech, in a SOT-23-6. 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 NC unconnected No internal connection. Leave floating or tie to VSS on the PCB; do not use as a routing via.
2 VDD power_in Positive supply / cell-voltage sense input. Operating range VDSOP1 = 1.5 V to 8 V (abs-max VSS-0.3 to VSS+10 V). Connect through a 100 Ω series resistor (R1) and 0.1 µF bypass capacitor (C1) to the monitored LiFePO4 cell's positive terminal. Typical IDD = 2.5 µA at VDD = 3.2 V.
3 VSS power_in Negative supply / ground reference. Connect to the monitored cell's negative terminal; all voltages in the datasheet are referenced to VSS.
4 NC unconnected No internal connection. Leave floating or tie to VSS.
5 NC unconnected No internal connection. Leave floating or tie to VSS.
6 OUT output Balance-control output driving the gate of the external balancing MOSFET. On -BB3A (feature-code A, N-MOSFET drive) OUT goes L→H (VOH ≥ VDD-0.1 V) when the cell voltage exceeds VCU = 3.600 ±0.025 V for the internal ~250 ms delay, turning on the N-MOSFET to bleed current through RB. Abs-max VOUT = VSS-0.3 to VDD+0.3 V; VOL ≤ 0.5 V.

Same part, different packaging or reel option.

  • HY2212-BB3A

CAD (KiCad official)

  • Symbol: HY2212-BB3A
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: hy2212-bb3a-etched.step / hy2212-bb3a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hy2212-bb3a.step / hy2212-bb3a.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
hy2212-bb3a.step 97 KB You want the bare part, or you mark your own boards.
hy2212-bb3a-etched.step 2.1 MB You want the part with HY2212-BB3A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 faces against 117 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: HYCON Tech datasheet (14 pp, sha256 b58c02aa982e12b3, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
