LP7802ASOF from LOWPOWER, in a SSOP-16-150mil. 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 | GND | power_in | Ground return. Tie to system ground; also connected to pin 5. |
| 2 | NC | unconnected | No connection. Leave floating (per application schematic pin 2 is not connected). |
| 3 | BAT | power_out | Battery pin. Internally connects the charger output and the boost converter (discharge) input. Bypass with ~10uF to GND. Typical float voltage 4.2V. |
| 4 | VIN | power_in | Charger input supply. Operating range 4.5V to 6V; absolute max 30V. OVP threshold ~6.5V. Bypass with 1uF to GND. |
| 5 | GND | power_in | Ground return (second GND pin, tied internally to pin 1). |
| 6 | ISET | input | Charge current programming pin. Resistor to GND sets IBAT (e.g. RISET=10K → 100mA, RISET=2K → 500mA). Leave open (NC) for default input current limit ~400uA. |
| 7 | NTC | input | Battery temperature protection sense input. Connect to an NTC thermistor divider from VIN. High-temp threshold ~6%·VIN falling, low-temp threshold ~43%·VIN rising, ~20mV hysteresis. |
| 8 | LED2 | output | Discharge status indicator LED drive (open-drain / current source, typical ILED = 3mA). Drives an LED to ground with series limit as needed. |
| 9 | LED1 | output | Charge status indicator LED drive (typical ILED = 3mA). |
| 10 | IEND2 | input | Discharge channel 2 end-of-discharge / no-load cut-off current setting pin. Resistor to GND programs the cutoff (RIEND=20K → 10mA, RIEND=10K → 20mA). tEND ≈ 16s of sub-threshold load before cutoff. |
| 11 | IEND1 | input | Discharge channel 1 end-of-discharge / no-load cut-off current setting pin. Same programming as IEND2. |
| 12 | EN | input | Enable / shutdown control for the boost output. High (VEN_H ≥ 1.4V) enables output; low (VEN_L ≤ 0.4V) disables it. Marked 'SD' on the top-view pinout drawing but described as EN in the pin-function table. |
| 13 | OUT1 | power_out | Discharge output channel 1 (from the 5V boost, up to 500mA). Bypass with 1uF to GND. |
| 14 | OUT2 | power_out | Discharge output channel 2 (from the 5V boost, up to 500mA). Bypass with 1uF to GND. |
| 15 | PMID | power_out | Boost converter output rail (~5V typical). Requires ~10uF bypass capacitor to GND. |
| 16 | LX | power_out | Boost converter switching node. Connect a 4.7uH inductor from LX to BAT. Absolute max -0.3V to 12V; 1MHz switching frequency. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 616 faces against 267 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.
