R5460N210AD-TR-FE from Ricoh Elec Devices, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DOUT | output | Output pin for over-discharge detection and protection (CMOS output), with a high level equal to VDD and a low level equal to VSS. |
| 2 | COUT | output | Output pin for over-charge detection and protection (CMOS output), whose low level is set by the V- pin voltage and whose high level is VDD. |
| 3 | V- | power_in | Negative input pin for the charger; it is pulled to VSS by an internal discharge-overcurrent release resistor (25 to 75 kΩ, typ. 40 kΩ) and its voltage sets the charge/discharge overcurrent thresholds. |
| 4 | VC | input | Monitoring input for the intermediate voltage between the two series-connected cells. |
| 5 | VDD | power_in | Power supply pin that also provides the IC substrate potential; the operating input voltage (VDD-VSS) is 1.5 V to 10.0 V and the absolute maximum rating is -0.3 V to 12 V. |
| 6 | VSS | power_in | Ground pin of the IC. |
