Lingyang Micro · Brushed DC Motor Drivers · SOT-23-6
LY3205 from Lingyang Micro, 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 | BAT | power_in | Battery terminal for the external lithium battery, with 4.2 V float voltage, 2.9 V over-discharge protection threshold and 5 µA standby current stated for this pin. |
| 2 | GND | power_in | Ground connection. |
| 3 | VIN | power_in | USB charging 5 V input supply, with 4.5 V to 6 V operating range and -0.3 V to 6 V absolute maximum rating. |
| 4 | KEY | input | Push-button pin where a single click toggles the output switch on or off. |
| 5 | VM | output | Motor negative terminal, rated for 2.6 A peak and 1.6 A continuous absolute maximum, with overcurrent protection at 2.6 A for LY3205 or 1.8 A for LY3205L. |
| 6 | LED | output | Indicator output for charging (red), full charge (green), discharging (green) and low battery (green blinking at 0.5 Hz below 3.2 V); no drive current or voltage limit is given for this pin. |
