DW03

Slkor SLKORMICRO Elec · Battery Management · SOT-23-5

DW03 from Slkor SLKORMICRO Elec, in a SOT-23-5. 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 VT passive Test pin; the datasheet names it only as a test pin and gives no function or electrical limits for it.
2 GND power_in Ground pin; connect the negative terminal of the battery to this pin.
3 VDD power_in Power supply pin; the VDD input pin voltage is rated -0.3 V to +6.0 V absolute maximum.
4 VM input Connects to the negative terminal of the charger and to the internal discharge FET switch, which connects this terminal to GND; VM input pin voltage is rated -6.0 V to +10 V absolute maximum.
5 VM input Connects to the negative terminal of the charger and to the internal discharge FET switch, which connects this terminal to GND; VM input pin voltage is rated -6.0 V to +10 V absolute maximum.
