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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HYCON Tech |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `HY2212-BB3ABB3A`++## CAD (KiCad official)++- Symbol: `HY2212-BB3A`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HYCON Tech datasheet](docs/hy2212-bb3a-datasheet.pdf) (14 pp, sha256 `b58c02aa982e12b3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
