Analysis of this circuit is simplified by the fact that the output has only two states: V out low (Vol) or V out hi (Voh). In this circuit, Voh is equal to the positive supply voltage and Vol is ...
Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...
This circuit is a very simple voltage monitoring device for +5V VCC supply lines. It can be used to monitor the power supply of a microcontroller (uC) by indicating when the supply level raises above ...
