Title: Backup power source circuit for control circuit
Inventor: KAN YOSHIKI
IPC: G06F1/24
Filed: 1984-11-07
Abstract: When application of a main supply voltage 2 to a control circuit 1 is suspended, a backup voltage 7 is supplied via a diode 8 to the circuit 1 to maintain predetermined operating conditions in the circuit 1. If, during supply of the voltage 2 to the circuit 1, the backup voltage 7 is lower than a predetermined level, a reset signal is applied to the circuit 1 by means of a reset circuit comprising a comparator 6 and a differentiator 9, 10, 11. Comparator 6 compares the voltage 7 with the voltage normally applied to circuit 1 from supply 2 via a constant voltage circuit 4 and a diode 5. If, during supply of voltage 2 to circuit 1, the voltage 7 is higher than the predetermined level, no current flows from supply 7 to circuit 1 because the forward voltage of diode 8 is much higher than that of diode 5. The circuit 1 may be an audio device for a vehicle, supply 2 being the vehicle battery and supply 7 being a battery built into the audio device. The reset signal may erase the contents of a memory or counter. <IMAGE>
