Abstract
A semiconductor apparatus is disclosed, including: multiple parallel monitor circuits each configured to control charge to a capacitor by controlling a transistor that bypasses, if the voltage of the capacitor exceeds a predetermined reference voltage, charge current provided to the capacitor. The semiconductor apparatus further includes high voltage side IC connection output terminals each connected to an open drain of N channel transistor; high voltage side IC connection input terminals each connected to a terminal of a high resistance component and to an inverter input terminal; low voltage side IC connection output terminal each connected to an open drain of P channel transistor; and low voltage side IC connection input terminal each connected to a terminal of a high resistance component and to an inverter input terminal.
