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 gate of the external N-MOSFET (M1) that controls the discharge current path; pulled low (V_DL ≤ 0.5V) to disable discharging when overdischarge or discharge overcurrent is detected, otherwise driven high (VDD-0.1V min). |+| 2 | OC | output | Charge-control MOSFET gate drive output. Drives the gate of the external N-MOSFET (M2) that controls the charge current path; pulled low (V_CL ≤ 0.5V) to disable charging when overcharge or charge overcurrent is detected, otherwise driven high (VDD-0.1V min). High-voltage tolerant (absolute max VDD-33 to VDD+0.3 V). |+| 3 | CS | input | Overcurrent-sense input and charger-detection terminal. Monitors the voltage across the external discharge/charge MOSFETs to detect discharge overcurrent (V_DIP=200mV), charge overcurrent (V_CIP=-200mV), and load short-circuit (V_SIP=1.0V typ.). High-voltage design tolerates VDD-33 to VDD+0.3 V so it can survive a reversed charger connection; typically connected to PB- through R3 (2kΩ). |+| 4 | VC | input | Middle-cell tap: connects to the negative terminal of battery 1 and the positive terminal of battery 2. Used by the internal detectors to monitor each cell voltage individually; typically connected through a 330Ω series resistor (R2) with a 0.1µF decoupling cap (C2) to VSS. |+| 5 | VDD | power_in | Positive supply input; connects to the positive terminal of battery 1 (pack +). VDD-VSS operating range 1.5V to 10V (absolute max VSS-0.3 to VSS+10V). Typically fed through a 330Ω series resistor (R1) with a 0.1µF decoupling cap (C1) to VSS. |+| 6 | VSS | power_in | Ground / negative supply input; connects to the negative terminal of battery 2 (bottom cell −). Serves as the reference for all internal detectors and MOSFET gate drivers. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HYCON Tech HY2122 EB1A |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `HY2122 EB1A`+- `HY2122 EB1AAB1A`+- `HY2122 EB1AAB1B`+- `HY2122 EB1ABB1A`++## CAD (KiCad official)++- Symbol: `HY2122 EB1A`+- 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 HY2122 EB1A datasheet](docs/hy2122-eb1a-datasheet.pdf) (20 pp, sha256 `c26f84e2ed2575c5`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
