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 | OD | output | Discharge-control MOSFET gate drive output. Drives the external N-MOSFET (M1) that gates the discharge current path. Output HIGH (V_DH ≥ VDD-0.1V) enables discharge; output LOW (V_DL ≤ 0.5V) during overdischarge or discharge overcurrent disables it. |+| 2 | CS | input | Overcurrent detection input and charger detection terminal. Senses the voltage across the two series N-MOSFETs (via R2, typ 2kΩ) to detect discharge overcurrent (V_DIP=150±25mV), charge overcurrent (V_CIP=-100mV), and load short-circuit (V_SIP=0.85V). High-voltage tolerant: absolute maximum VDD-20V to VDD+0.3V (rated 20V for charger-reverse protection). |+| 3 | OC | output | Charge-control MOSFET gate drive output. Drives the external N-MOSFET (M2) that gates the charge current path. Output HIGH (V_CH ≥ VDD-0.1V) enables charging; output LOW (V_CL ≤ 0.5V) during overcharge or charge overcurrent disables it. High-voltage tolerant: absolute maximum VDD-20V to VDD+0.3V. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie as convenient for PCB routing. |+| 5 | VDD | power_in | Positive power supply input, connected to the battery positive terminal through R1 (typ 100Ω). Operating range 1.5V to 8V (V_DSOP1); absolute maximum VSS-0.3V to VSS+10V. Bypass to VSS with C1 (typ 0.1μF, min 0.01μF). |+| 6 | VSS | power_in | Negative power supply input / ground reference. Connected to the battery negative terminal (cell ground, not pack ground). All internal detection voltages are referenced to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HYCON Tech |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `HY2111-GBGB`++## CAD (KiCad official)++- Symbol: `HY2111-GB`+- 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/hy2111-gb-datasheet.pdf) (18 pp, sha256 `f1cf4ba2fb7a51df`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
