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 | CHRG | tri_state | Open-drain charge-status indicator output; outputs 2 Hz pulse during charging, continuous low level at end of charge, and high-impedance during sleep mode or battery over-temperature/over-cold; sink current ICHRG = 10 mA (typ) at VCHRG = 0.3 V (charge-complete state), leakage 1 µA max at VCHRG = 6 V in sleep mode. |+| 2 | GND | power_in | Power-supply ground return; PCB copper area on this pin should be maximized to improve thermal dissipation from the SOT-23-6 package. |+| 3 | BAT | power_out | Battery positive terminal; delivers trickle, constant-current (up to 400 mA), and constant-voltage (4.2 V ±1%) charge current to the battery; battery leakage current < 3 µA in sleep mode or when VIN is below the UVLO threshold (2.65 V typ). |+| 4 | VIN | power_in | Supply voltage input, 4.5 V to 6.0 V; powers all internal circuits; CN3142 enters low-power sleep mode when VIN − VBAT < 10 mV and exits sleep when VIN − VBAT rises above 60 mV; quiescent current 280-500 µA (BAT open). |+| 5 | TEMP | input | Battery temperature monitor input; pin sources 30 µA (typ) through an external 10 kΩ NTC resistor to GND; charging suspends when VTEMP < 100 mV (over-hot) or > 850 mV (over-cold); charge current reduced to 50 % ICC when 100-135 mV (warm) or 25 % ICC when 550-850 mV (cool); connect fixed 10 kΩ to GND if temperature monitoring is not used. |+| 6 | ISET | passive | Constant-current set and charge-current monitor; connect resistor RISET from this pin to GND; ICH = 502 V / RISET (A, Ω); pin voltage regulated to 0.4 V (typ) in trickle mode and 1.205 V (typ) in CC mode, allowing current monitoring via ICH = (VISET × 417) / RISET; over-current protection shuts down the device if charge current exceeds 0.47 A (typ) for more than 2 ms (typ). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23-6 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `CN3142`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)+- 3D model files: `cn3142-etched.step` / `cn3142-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cn3142.step` / `cn3142.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ShangHai Consonance Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590904927466713088) (11 pp, sha256 `bbc80ba3304aaf98`, retrieved 2026-09-22, tier: lcsc)+- **Datasheet language:** Chinese.
