... As shown in the block diagram in Fig battery voltage is divided by the VR and input to the input Pin3 in accord- ance with rotation amount. The voltage at the output Pin1 is controlled by the AN8353UB so that the duty of the ON/OFF period of the external output transistor will be proportional to the input voltage, thus controlling a current flowing to the lamps of the dashboard, etc ...
