LY3205E 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 connected to the external lithium battery, which powers the device and is charged through this pin; the battery is protected against over-discharge at 2.9 V (VOD) and the absolute maximum rating for this pin is -0.3 V to 6 V. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | VIN | power_in | USB 5 V charger input; the datasheet gives an operating range of 4.5 V to 6 V (5 V typical) and an absolute maximum of -0.3 V to 6 V. |
| 4 | EN | input | Active-high enable that may be driven by a switch or an MCU and must not be left floating; the datasheet lists VENH = 0.9 V and VENL = 0.5 V. |
| 5 | VM | output | Motor negative terminal driving the motor; the peak current is 2.6 A, the continuous current is 1.6 A absolute maximum, and the overcurrent protection threshold is typically 2 A. |
| 6 | LED | output | Indicator pin for charging, discharging and low-battery status; the datasheet gives a low-battery flash frequency of 0.5 Hz when VBAT is below 3.2 V and no drive current limit. |
