CN3062 from ShangHai Consonance Elec, in a SOIC-8-EP. 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 | TEMP | input | Battery NTC temperature sense input; charging is suspended if TEMP is below 47% or above 84% of VIN for more than 0.15 s, and tying TEMP to GND disables temperature monitoring. |
| 2 | ISET | passive | Sets the constant charge current through an external resistor to GND (ICH = 1800 V / RISET), with the pin held at 0.2 V in precharge and 2 V in constant-current mode, and can be used to monitor ICH = (VISET × 900) / RISET. |
| 3 | GND | power_in | Ground reference for the charger; the exposed metal pad on the package underside should be soldered to a large PCB ground copper area for maximum charge current. |
| 4 | VIN | power_in | Positive input supply for the internal circuits, specified at 4.35 V to 6 V, with the device entering low-power sleep mode when VIN is within 20 mV of BAT and absolute maximum pin voltage of -0.3 V to 6.5 V. |
| 5 | BAT | power_out | Battery connection that delivers charge current and the regulated 4.2 V charge voltage, drawing less than 3 µA in UVLO or sleep mode. |
| 6 | DONE | output | Open-drain charge-complete indicator that is pulled low when charging terminates at 10% of the constant-charge current and is high-impedance otherwise (10 mA sink at 0.3 V, 1 µA leakage at 6 V). |
| 7 | CHRG | output | Open-drain charging-status indicator that is pulled low while charging and is high-impedance otherwise (10 mA sink at 0.3 V, 1 µA leakage at 6 V). |
| 8 | FB | input | Kelvin sense input for the battery positive terminal that sets the 4.2 V ±1% regulated voltage, where a resistor Rx between FB and BAT raises it per Vbat = 4.2 + 3.04×10^-6 × Rx. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
