Claims (1)
ンサを充電することにより徐々に上昇する電圧を出力し
かつ電源スイツチオフ時には上記時定数より十分少さい
時点数でコンデンサを放電させてその出力を急速に低下
させるように構成した充放電回路と、電源スイツチオン
時点から上記充放電回路の出力電圧が予め設定された基
準値をこえる時点までの間にパルスを出力するパルス生
成回路とからなることを特徴とするパルス発生回路。When the power switch is turned on, a voltage that gradually rises is output by charging the capacitor with a preset time constant, and when the power switch is turned off, the capacitor is discharged at a number of times sufficiently smaller than the above time constant to rapidly increase the output. and a pulse generation circuit that outputs pulses from the time when the power supply is turned on until the output voltage of the charge/discharge circuit exceeds a preset reference value. Pulse generation circuit.
