COMPONENTS DESCRIPTION
When a base gose Hi, ACC voltage is detected
While BU is applied, BU5V AVR outputs 5V
When Q510's base goes Hi, A8V AVR outputs 8.0V
When Q572's base goes Lo, REMO.5V AVR outputs 5V
When base goes Hi, USB5V AVR turns off
When base goes Hi, USB3.3V AVR turns off
When Q907's base goes Hi, SW16V outputs (BU–0.6)V
