LOWPOWER · Battery Management · SOT-23-6

LP78080B6F from LOWPOWER, in a SOT-23-6. 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 BAT power_out Li-ion battery positive terminal. Connects to the single-cell Li-ion battery (typ. 4.2 V float, 4.04 V recharge threshold). Acts as charger output during charging and as supply input for the fan driver when the adapter is absent. Recommended 10 uF ceramic decoupling to GND.
2 GND power_in Device ground / power return.
3 OUT output Fan positive-terminal PWM drive output. Drives a brushed-DC fan motor via an internal PMOS at 3 selectable duty cycles: 50/75/100 % on battery power, 35/60/80 % on adapter power. Short-circuit protection trips when VBAT - VOUT > ~500 mV (hiccup mode, 30 ms period). Absolute max -0.3 V to +110 V. Place 10 uF cap close to the motor.
4 LED output Open-drain LED status control. Sinks ~4 mA to indicate charge state: solid = fully charged / adapter present with normal input, 0.8 Hz blink = charging or adapter under-voltage, 3.1 Hz blink = battery low (2.8 V < VBAT <= 3.1 V, adapter absent), off = reverse battery or VBAT out of range. Absolute max -0.3 V to +11 V.
5 KEY input Single-button user control input with 40 ms debounce. Each press cycles fan speed Fan1 -> Fan2 -> Fan3 -> Off. Typically tied to a momentary push-button to GND. Absolute max -0.3 V to +12 V.
6 VIN power_in Charger adapter input. Operating range 4.4 V to 5.5 V (typ. 5 V); adaptive-current loop starts reducing charge current when VIN falls to 4.4 V. UVLO rising 3.7 V, falling 3.45 V. Absolute max -0.3 V to +10 V. Recommended 10 uF ceramic decoupling to GND.
