Figure 1 shows an example of on/off circuitry commonly used in battery-operated devices. The P-channel MOSFET, Q1, serves as a power switch. When you push the on button, S1, Q1 ' s gate goes low. Q1 turns on and supplies battery voltage to the DC-to converter. Depending on the battery voltage in the device, the DC-to converter might convert the voltage either up or down. In either case, it supplies VCC to Theµc. Theµc goes through its power-up softwar
