With this application, it can obtain that decrease of IC power consumption, and the applied voltage exceeds IC rating 5.5V. That application is shown in below Figure 8. The coil power supply is connected to high voltage source applied from adapters. Then the IC power supply is connected to the power supply that should be different from the coil power supply.
