NSL2020B
WXNSIC · Battery Management · SOT-23-6
NSL2020B from WXNSIC, 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 | VDD | power_in | Battery positive connection, tied to the cell positive terminal; absolute maximum supply voltage is -0.3 V to 4.5 V referenced to GND. |
| 2 | GND | power_in | Chip ground, connected to the battery negative terminal; all voltage ratings are referenced to this pin. |
| 3 | VCC | power_in | Charging port that accepts charger input (the datasheet states the chip can take power directly from a USB port); no voltage limit for this pin is given in the text. |
| 4 | SW | input | Signal input connected to the microphone (pneumatic) sensor; absolute maximum voltage is -0.3 V to VDD+0.3 V. |
| 5 | LED | output | Drive output for the working indicator LED; absolute maximum voltage is -0.3 V to VDD+0.3 V, and the LED output current is specified as 5 mA. |
| 6 | AT | output | Drive-current output connected to the load, switched by the integrated discharge MOS (RDS,ON 80 mΩ typ., 5 A discharge overcurrent threshold); absolute maximum voltage is -0.3 V to 6 V and recommended discharge current is up to 3.5 A. |
