Seaward Elec · Battery Management · SOT-23-6
SE9013-HF from Seaward Elec, 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 | CHRG | output | Charge status output that drives the LEDs: the datasheet says it is driven High during charging to turn on the red LED and driven Low when charging is finished to turn on the green LED. |
| 2 | GND | power_in | Ground reference pin for the charger. |
| 3 | BAT | power_out | Charge current output that supplies charge current to the battery and regulates the final float voltage to 1.4 to 4.2V. |
| 4 | VCC | power_in | Positive input supply that powers the charger; the pin description gives a range of 3.5 to 6.5V and says it should be bypassed with at least a 1µF capacitor. |
| 5 | FB | input | Voltage feedback input internally referenced to 1.20V, used to program the battery float voltage from 1.4 to 4.2V. |
| 6 | PROG | bidirectional | Charge current program, charge current monitor and shutdown pin, where a 1% resistor to ground sets the charge current (battery current is 1060 times the PROG current) and PROG voltage falling below 100mV for longer than about 1ms ends charge indication. |
