Parallel monitor circuit and semiconductor apparatus

摘要

A parallel monitor circuit ( 1 A) for monitoring one (C 1 ) of serially connected plural capacitors (Cn) receiving a direct recharging current is disclosed. The circuit comprises a bypassing transistor (Q 1 ) for bypassing the capacitor (C 1 ) with the recharging current when the capacitor voltage (VSo 1 ) exceeds a monitor voltage (Vr 1 ) determined by a voltage setting circuit in order to equally recharge the capacitors. A transferring unit transfers a voltage control circuit (VS 1 ) and an internal circuit connected to the voltage control circuit to a standby mode when the voltage control circuit receives a specific combination of voltage codes (RC 1 ).
