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 | DOUT | output | CMOS output pin for over-discharge detection. Drives the gate of the discharge-control external MOSFET; switches to 'L' after the internal fixed delay (128 ms) when cell voltage falls below the over-discharge threshold (2.0-3.0 V range). |+| 2 | COUT | output | CMOS output pin for over-charge detection. Drives the gate of the charge-control external MOSFET; switches to 'L' after the internal fixed delay (1.0 s) when cell voltage exceeds the over-charge threshold (4.1-4.5 V for A/C/E/F, 3.5-4.0 V for D versions). |+| 3 | V- | input | Charger negative input pin. Senses the voltage at the pack negative terminal to detect excess discharge/charge currents and short circuit; absolute rating VDD−30 V to VDD+0.3 V. |+| 4 | VC | input | Input pin for the center (middle) voltage tap between the two series cells. Provides the per-cell sense used by the VD1U/VD1L/VD2U/VD2L detectors. Absolute rating VSS−0.3 V to VDD+0.3 V. |+| 5 | VDD | power_in | Positive power supply pin, connected to the positive terminal of the upper cell; also serves as the IC substrate reference. Absolute maximum rating −0.3 V to 12 V (process withstands 30 V transients). |+| 6 | VSS | power_in | Ground pin for the IC; connected to the negative terminal of the lower cell (pack GND reference). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Ricoh Elec Devices |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `R5460N214AF-TR-FEN`+- `R5460N214AF-TR-FEK`++## CAD (KiCad official)++- Symbol: `R5460N214AF-TR-FE`+- 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:** [Ricoh Elec Devices datasheet](docs/r5460n214af-tr-fe-datasheet.pdf) (33 pp, sha256 `1b26c54b8790b19f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
