LP28013SQVF from LOWPOWER, in a TDFN-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input power source pin. Connect to a wall adapter; operating range 4.5V-6.5V with absolute maximum 28V and internal OVP at ~7V. Typically bypassed with a 1uF capacitor to GND. |
| 2 | CHRG | output | Open-drain charge status output. Pulled low (~5mA sink) by an internal NMOS while charging; high-impedance when the charge cycle completes. Requires an external pull-up resistor (e.g. through an indicator LED). |
| 3 | NC | unconnected | No connection. Leave floating or tie to GND per PCB layout preference. |
| 4 | EN | input | Charge enable input, active low. Logic-low threshold <=0.4V enables charging; logic-high threshold >=1.4V disables the charger. |
| 5 | NC | unconnected | No connection. |
| 6 | GND | power_in | Device ground reference. Tie to system ground along with the exposed pad (pin 11). |
| 7 | NC | unconnected | No connection. |
| 8 | NC | unconnected | No connection. |
| 9 | ISET | input | Charge current program pin. Connect a 1% resistor RISET from this pin to GND to set the constant-current charge level per IBAT = 1700 * VISET / RISET (VISET=1V typical). Charge termination is detected when the ISET pin voltage falls below 100mV for tTERM. |
| 10 | BAT | power_out | Battery connection pin. Provides regulated 4.2V float voltage and up to 1A charge current to a single-cell Li-Ion/Li-Polymer battery. Typically bypassed with a 10uF capacitor. |
| 11 | GND | power_in | Exposed thermal pad on the bottom of the TDFN-10 package. Must be soldered to the PCB ground plane for proper electrical grounding and thermal dissipation. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 525 faces against 74 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
