ShangHai Consonance Elec · Battery Management ICs · SOP-8-EP
CN3162 from ShangHai Consonance Elec, in a SOP-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 input: charging is suspended when TEMP is below 45% or above 80% of VIN, and tying TEMP to GND disables temperature monitoring. |
| 2 | ISET | passive | Constant-charge-current programming pin: an external resistor to GND sets the current via ICH = 1218V/RISET, with 0.12V in precharge and 1.205V in constant-current mode. |
| 3 | GND | power_in | Ground reference for the charger circuit. |
| 4 | VIN | power_in | Positive input supply for the internal circuitry, specified at 3.8V to 6V; the charger enters sleep mode when VIN is within 10mV of BAT. |
| 5 | BAT | power_out | Battery connection that supplies charge current and the constant-voltage charge voltage (4.2V nominal, ±1%); BAT leakage is below 3µA in sleep or under-voltage lockout. |
| 6 | DONE | output | Open-drain charge-complete indicator that is pulled low at end of charge and is high-impedance otherwise, with 10mA pull-down capability. |
| 7 | CHRG | output | Open-drain charge-status indicator that is pulled low while the charger is charging and is high-impedance otherwise, with 10mA pull-down capability. |
| 8 | FB | input | Battery-voltage Kelvin sense input that regulates the constant-voltage charge level; a resistor between FB and BAT raises the regulated voltage. |
| 9 | EP | power_in | Exposed thermal pad that must be connected to ground and soldered to the PCB ground copper for maximum heat dissipation. |
