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 that controls the discharge path; output high (~VDD-0.02V) enables discharge, output low (~0.1V) disables it during overdischarge, discharge overcurrent, or load short-circuit conditions. |+| 2 | CS | input | Overcurrent detection input / charger detection terminal. Senses the voltage drop across the pack negative path to detect discharge overcurrent (VDIP=50mV typ), load short-circuit (VSIP=0.58V typ), and charge overcurrent (VCIP=-50mV typ). High-voltage tolerant to VDD+25V for reverse-connected charger protection. |+| 3 | OC | output | Charge control MOSFET gate drive output. Drives the gate of the external N-MOSFET that controls the charge path; output high (~VDD-0.02V) enables charging, output low (~0.1V) disables it during overcharge or charge overcurrent conditions. High-voltage tolerant to VDD+25V for reverse-connected charger protection. |+| 4 | NC | unconnected | No connection. Leave floating or tie to any convenient net; no internal bond. |+| 5 | VDD | power_in | Positive power supply input, connected to battery positive through R1 (100Ω typ) with C1 (0.1μF typ) to VSS. Operating range 1.5V to 8V; absolute max VSS-0.3V to VSS+10V. Typical operating current 3.0μA at VDD=3.9V. |+| 6 | VSS | power_in | Ground / negative power supply input, connected directly to battery negative terminal. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XIN FEI HONG |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `FH9261-DBGDBG`++## CAD (KiCad official)++- Symbol: `FH9261-DBG`+- 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:** [XIN FEI HONG datasheet](docs/fh9261-dbg-datasheet.pdf) (18 pp, sha256 `3215be66c4cfc32f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
