Method and circuit arrangement for preventing the stand-by discharge of a battery-powered signal evaluation circuit of a sensor |
摘要 |
A circuit arrangement for preventing the discharge of a battery powering a signal evaluation circuit while the circuit is in a stand-by mode, provided with a sensor for generating signals and means responsive to the generation of signals for connecting the battery to the signal evaluation circuit and for disconnecting the battery in the absence of signals. The signal responsive means include an amplifier for triggering a monostable flip flop the output of which controls the conductivity of a transistor between the battery and the signal evaluation circuit.
