  • Patent number: 5886953
    Abstract: A heavy-load driving device for a electronic watch is provided that assures reliable timekeeping operation and enables proper drive in accordance with the power supply voltage level. When drive command circuit generates an alarm-coincidence signal Sa, this signal Sa causes a preparatory judging circuit 10 to operate, so as to make a judgment, in accordance with the reduced power supply voltage level under a given load condition, as to whether or not to allow drive of a beeper device 31, a drive-enabling signal Svm being output if the judgment is to allow drive. By doing this, a heavy-load voltage detection circuit 21 starts to output a drive-time judgment signal Pvh which indicates the power supply voltage level judgment results.
