CASE ANALYSIS
Scenario
A simplified USB rechargeable fan circuit using a TP4056 charger IC, Li-Ion battery, SPST power switch, potentiometer for speed control, and a resistor representing the fan motor load.
Key decisions
- Using TP4056 for Li-Ion charging
- Potentiometer as speed control
- Resistor dummy load for motor
When to reuse this
When instructing on basic portable fan electronics or battery charging systems with speed control.
