FIELD: electrical engineering.
SUBSTANCE: invention relates to a sensor determining a given current consumption threshold. Sensor consists of a current sensor, two N-channel MOSFET transistors, resistors, differential amplifiers of the upper and lower thresholds, which are connected in parallel with respect to each other to the output of the current sensor, the differential amplifier of the upper threshold is connected to the output of the current sensor by a non-inverting input, while its inverting input is connected to the reference point of the voltage through a voltage divider, made on resistors, the differential amplifier of the lower threshold is connected to the inverting input, while its non-inverting input is connected to the point of the reference voltage through a voltage divider, made on resistors.
EFFECT: technical result consists in expanding the functionality of the current sensor by adjusting the upper response threshold.
