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.
