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 | Over-discharge detection CMOS output. Drives the gate of the external discharge-control MOSFET. Goes 'L' after the internal fixed delay (128 ms typ) when a cell voltage falls below the over-discharge threshold; returns 'H' when release conditions are satisfied. |+| 2 | COUT | output | Over-charge detection CMOS output. Drives the gate of the external charge-control MOSFET. Goes 'L' after the internal fixed delay (1.0 s typ) when a cell voltage exceeds the over-charge threshold; returns 'H' after over-charge release. Also asserts on excess charge-current detection. |+| 3 | V- | input | Charger / load negative sense input. Sensed against VDD to detect excess discharge-current (VDET3 ≈ 0.05-0.2 V), excess charge-current (VDET4 ≈ -0.1 to -0.4 V), and short-circuit conditions (Vshort ≈ 1.1 V typ). Absolute max range VDD-30 V to VDD+0.3 V. |+| 4 | VC | input | Middle-point (center-tap) voltage input between the two series cells. Provides the reference node used by the cell-1 / cell-2 voltage detectors (VD1U/L, VD2U/L). Absolute max VSS-0.3 V to VDD+0.3 V. |+| 5 | VDD | power_in | Positive supply pin, tied to the positive terminal of the upper cell (2-cell stack). Also serves as the substrate reference of the IC. Absolute max -0.3 V to +12 V; V- detection references are all taken relative to VDD. |+| 6 | VSS | power_in | Ground / negative supply pin of the IC, tied to the negative terminal of the lower cell. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Ricoh Elec Devices |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `R5460N212AF-TR-FEN`+- `R5460N212AF-TR-FEK`++## CAD (KiCad official)++- Symbol: `R5460N212AF-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/r5460n212af-tr-fe-datasheet.pdf) (33 pp, sha256 `1b26c54b8790b19f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
