VOLTAGE DETECTION CIRCUIT
Abstract:
To provide a voltage detection circuit in which the influence on a detection voltage by semiconductor manufacturing variations is small and which is small in current consumption. A voltage detection circuit is provided which detects a voltage, based on an output signal of a detection circuit and outputs a detection signal. The detection circuit includes a first MOS transistor unit which allows a first current to flow, a second MOS transistor unit which allows a second current to flow, and a current voltage conversion unit which converts each of the first current and the second current into a voltage and outputs the same as the detection signal. A voltage characteristic of the first current and a voltage characteristic of the second current are configured so as to be crossed with each other at a predetermined voltage.
